The L TC®5588-1 is a direct conversion I/Q modulator designed for high performance wireless applications. It allows direct modulation of an RF signal using differential baseband I and Q signals. It supports L TE, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA, WiMax and other communication standards. It can also be config- ured as an image reject upconverting mixer , by applying 90° phase-shifted signals to the I and Q inputs. The I/Q baseband inputs drive double-balanced mixers. An on- chip balun converts the differential mixer signals to a 50Ω single-ended RF output. Four balanced I and Q baseband input ports are DC-coupled with a common mode volt- age level of 0.5V . The LO path consists of an LO buffer with single-ended or differential inputs and precision quadrature generators to drive the mixers. The supply voltage range is 3.15V to 3.45V . An external voltage can be applied to the LINOPT pin to further improve 3rd-order linearity performance. Accurate temperature dependent calibrations can be performed using the on-chip thermistor . 200MHz to 6000MHz Direct Conversion T ransmitter Application

EN (Pin 1): Enable Input. When the enable pin voltage is higher than 2V , the IC is on. When the input voltage is less than 1V , the IC is off. GND (Pins 2, 5, 8, 11, 12, 14, 17, 19, 20, 23, Exposed Pad Pins 25 and 26): Ground. Pins 2, 5, 8, 11, 20, 23 and exposed pad Pin 25 (group 1) are connected together internally while Pins 12, 14, 17, 19 and exposed pad Pin 26 (group 2) are tied together and serve as the ground return for the RF balun. For best overall performance all ground pins should be connected to RF ground. For best OIP2 performance it is recommended to connect group 1 and group 2 only at second and lower level ground layers of the PCB, not the top layer . A thermistor (temperature variable resistor) of 1.4kΩ at 25°C and V CC = 3.3V with temperature coefficient of 11Ω/°C is connected between group 1 and group 2. LOP (Pin 3): Positive LO Input. An AC-coupling capacitor (1nF) in series with 50Ω to ground provides the best OIP2 performance. LOM (Pin 4): Negative LO Input. An AC-coupled 50Ω LO signal source can be applied to this pin. NC (Pins 6, 13, 15): No Electrical Connection. LINOPT (Pin 7): Linearity Optimization Input. An external voltage can be applied to this pin to optimize the linearity (OIP3) under a specific application condition. Its optimum voltage depends on the LO frequency, temperature, supply voltage, baseband frequency and signal bandwidth. The typical input voltage range is from 2V to 3.7V . The pin can be left floating for good overall linearity performance. BBMQ, BBPQ (Pins 9, 10): Baseband Inputs of the Q Chan- nel. The input impedance of each input is about –3kΩ. It should be externally biased to a 0.5V common mode level. Do not apply common mode voltage beyond 0.55V DC. RF (Pin 16): RF Output. The RF output is a DC-coupled single-ended output with 50Ω output impedance at RF frequencies. An AC-coupling capacitor of 6.2pF (C7), should be used at this pin for 0.7GHz to 3.5GHz operation. V CC1, VCC2 (Pins 24, 18): Power Supply. It is recommended to use 2 × 1nF and 2 × 4.7μF capacitors for decoupling to ground on these pins. BBPI, BBMI (Pins 21, 22): Baseband Inputs of the I Channel. The input impedance of each input is about –3kΩ. It should be externally biased to a 0.5V common mode level. Do not apply common mode voltage beyond 0.55V DC. 90° I CHANNEL Q CHANNEL VqI VqI RF EN GND LOP LOM NC LINOPT 3118 GND 24 18 NC 13 15 BBPI BBMI BBPQ BBMQ 252320 GND 764 55881 BD GNDRF VCC1 VCC2 2612 14 19
