Description

The MASL-011023 is a plastic packaged high power switch-limiter with integrated bias networks. This surface mount, small configuration is designed with minimal parasitics usually associated with hybrid MIC designs incorporating beam lead and/or bondable PIN diodes that require chip and wire assembly. This standard HQFN enables reliable, repeatable high volume manufacturing with MACOMs’ design techniques to maximize heat dissipation in a plastic package. This SP2T switch -limiter is designed to optimize Ant to R X loss and handle +51 dBm CW through the TX path to an external high power 50 Ω termination. This device incorporates a high power SP2T switch, a limiter function, and a fully integrated RF & DC bias network. The MASL -011023 is designed to be used in 2.7 -

3.5 GHz higher power switch applications that

require high volume, surface mount, solder reflow manufacturing. It is RoHS compliant, durable, reliable and capable of meeting all military, commercial, and industrial environments. Pin No. Pin Name Description

Current is controlled externally, with RRX in parallel with a switching diode. ―Rcom‖ is 220 Ω. G1 is connected to ground externally. See Application Circuit Diagram. Bias Control Optimal operation is achieved by simultaneous application of positive DC voltage to the low loss switching arm and negative DC voltage to the isolating switching arm. In the low loss state, the diode is forward biased with current. In the isolated state, the series diode is reverse biased with voltage. Minimum Reverse Bias Required (TX mode):

30 V DC Voltage for 125 W CW Power

Proper ESD control techniques should be used when handling these devices. 3. Exceeding any one or combination of these limits may cause permanent damage to this device. 4. MACOM does not recommend sustained operation near these survivability limits. 5. Operating at nominal conditions with TJ ≤ +175°C will ensure MTTF > 1 x 106 hours. 6. TX path typical thermal resistance (Өjc) = 12.6° CW dissipated.
