Quad Bias Driver for GaAs FET and PIN Diode Switches MADRMA0001 & 2 MADR-007690-DR0002 Description The MADRMA0001 family of quad bias drivers can either be configured to translate TTL signals into the negative voltages required for GaAs FET switches or attenuators or they can be used to produce up to ± 40 mA per channel for biasing series or shunt PIN diode switches. Each channel contains Inverting and Non-Inverting Outputs for logic flexibility. Designed with high-speed CMOS technology, the drivers achieve high performance with very low power dissipation.

Quad Bias Driver for GaAs FET and PIN Diode Switches MADRMA0001 & 2 MADR-007690-DR0002 Application Information • • • • • • The input logic voltage (V in) cannot exceed the positive supply (Vcc) by more than 0.5 V nor go below GND by more than 0.5 V. The input current should not exceed ± 25 mA. This device should be treated as any TTL CMOS circuit. Pull-up/down resistors should tie to Vcc or GND. Non-used inputs must be tied to GND. Decoupling caps (0.1 uF) should be used on Vcc and Vee, and the output current should be limited to ± 40 mA. Logic “0” sets J0 to J1 to low loss state Limiting Resistors (R2, R3) set for +/- 20 mA output current The value of the limiting resistors (R2, R3) is determined by the following: R1 = [(Vcc - Vdiode)/I desired] - Rout Driving PIN Diode Switches: Driving FET Switches: 5 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.
