Description

The MSW2010 -201 (50 MHz - 1 GHz) and MSW2011-201 (400 MHz - 4 GHz) series of surface mount silicon PIN diode SP2T switches can be used for high power transmit/receive (TR) switching or active receiver protection. These switches are manufactured using a proven hybrid manufacturing process incorporating high voltage PIN diodes and passive devices integrated on a ceramic substrate. These low profile, compact, surface mount components offer superior small and large signal performance compared to that of MMIC devices in QFN packages. The SP2T switches are designed in an asymmetrical topology to minimize Tx -Ant loss and maximize Tx-Rx isolation performance. The very low thermal resistance (<10ºC/W ) of the PIN diodes in these devices enables them to reliably handle RF incident power levels of 50 dBm CW and RF peak incident power levels of 53 dBm in cold switching applications at T A = 85ºC. The thick I layers of the PIN diodes, coupled with their long minority carrier lifetime, provides input third order intercept point (IIP3) greater than 60 dBm. The MSW2010 -201 and MSW2011 -201 SP2T switches are designed to be used in high average and peak power switch applications, operating from

50 MHz to 4 GHz in two bands, which utilize high

volume, surface mount, solder re -flow manufacturing. These products are durable and capable of reliably operating in military, commercial, and industrial environments.

PIN diode DC reverse voltage to maintain high resistance in the OFF PIN diode is determined by RF frequency, incident power, and VSWR as well as by the characteristics of the diode. The minimum reverse bias voltage values are provided in this datasheet. The input signal level applied for small signal testing is approximately 0 dBm. 2. Switching time (50% TTL - 10/90% RF Voltage) is a function of the PIN diode driver performance as well as the characteristics of the diode. An RC “current spiking network” is used on the driver output to provide a transient current to rapidly remove stored charge from the PIN diode. Typical component values are: R = 50 to 220 Ω and C = 470 to 1,000 pF. MACOMs MPD2T28125-700 is the recommended PIN diode driver to interface with the MSW2010-201 and MSW2011-201 SP2T switches.

Each evaluation board includes the appropriate MSW201x -200 switch, DC blocking capacitors at each RF port and bias decoupling networks at each RF port which allow DC or low frequency control signals to be applied to the switch. Three complementary control signals are required for proper operation. Bias voltages are applied to the TX bias port, RX bias port and the DC bias port to control the state of the switch. A bias voltage of 5 V must be applied to the Ant Bias (pin 3 of multi -pin connector P1) port whenever the switch is in operation.

For further information and support please visit: https://www.macom.com/support DS-xxxxxxx Transmit State In the TX state, the series PIN diode between the ANT and TX ports is forward biased by applying 0 V to the TX bias input port (pin 1 of multi -pin connector P1). The magnitude of the resultant bias current through the diode is primarily determined by the voltage applied to the ANT bias port (pin 3 of J1), the magnitude of the forward voltage across the PIN diode and the resistance of R1. This current is nominally 100 mA. At the same time, the PIN diode connected between RX and DC ports is also forward biased by applying a higher bias voltage, nominally

28 V, to the RX bias port (pin 7 of P1) and 0 V to the

DC bias port (pin 5 of P1). Under this condition, the PIN diode connected between the ANT and RX port is reverse biased and the PIN diode connected between the RX and DC ports is forward biased. The magnitude of the bias current through this diode is primarily determined by the voltage applied to the RX bias port, the magnitude of the forward voltage across the PIN diode and the resistance of R2. This current is nominally 25 mA. The RX series PIN diode, which is connected between the ANT and RX ports, must be reverse biased during the transmit state. The reverse bias voltage must be sufficiently large to maintain the diode in its non -conducting, high impedance state when large RF signal voltage may be present in the ANT-to-TX path. The reverse voltage across this diode is the arithmetic difference of the bias voltage applied to the RX bias port and the DC forward voltage of the forward -biased transmit series PIN diode. The minimum voltage required to maintain the series diode on the RX side of the switch out of conduction is a function of the magnitude of the RF voltage present, the standing wave present at the RX series diode’s anode, the frequency of the RF signal and the characteristics of the RX series diode, among other factors. Minimum control voltages for several signal frequencies are shown in the table “Minimum Reverse Bias Voltage”, assuming the input power to the RX or ANT port to be 100 W CW and the VSWR on the ANT -TX path to be 1.5:1. It is important to note that the evaluation board, as supplied from the factory, is not capable of handling RF input signals larger than 45 dBm. If performance of the switch under larger input signals is to be evaluated, an adequate heat sink must be properly attached to the evaluation board, and several of the passive components on the board must be changed in order to safely handle the dissipated power as well as the high bias voltage necessary for proper performance. Contact the factory for recommended components and heat sink. Receive State In the RX state, the series PIN diode between the ANT and RX ports is forward biased by applying 0 V to the RX bias input port (pin 7 of multi-pin connector P1). The magnitude of the resultant bias current through the diode is primarily determined by the voltage applied to the ANT bias port (pin 3 of P1), the magnitude of the forward voltage across the PIN diode and the resistance of R1. This current is nominally 100 mA. At the same time, the PIN diode connected between RX and DC ports is reverse biased by applying a high bias voltage, nominally 28 V, to the DC bias port (pin 5 of P1). A high voltage, nominally 28 V, is also applied to the TX bias port (pin 1 of P1). Under this condition, the PIN diode connected between the ANT and TX port is reverse biased thus isolating the TX RF port from the RX signal path. The reverse voltage across this diode is the arithmetic difference of the bias voltage applied to the TX bias port and the DC forward voltage of the forward -biased receive series PIN diode. The minimum voltage required to maintain the series diode on the TX side of the switch out of conduction is a function of the magnitude of the RF voltage present, the standing wave present at the RX series diode’s anode, the frequency of the RF signal and the characteristics of the TX series diode, among other factors. For typical receive -level signals, this diode is held out of conduction with a relatively small reverse bias voltage. The values of the reactive components which comprise the bias decoupling networks as well as the signal path DC blocking are shown in the table RF Bias Network Component Values. Reference Path A reference path is provided on the evaluation board, complete with bias decoupling networks, so that the magnitude of the insertion loss of the micro- strip transmission lines connected to the switch and the associated bias decoupling components can be measured and removed from the measured performance of the switch.
