Operation of the MA4SW610B-1 Switch

The simultaneous application of negative DC current to the low loss port and positive DC current to the

remaining isolated ports as shown in the schematic provides successful RF operation of the MA4SW Series of

PIN Diode Switches. The backside area of the die is the RF and DC return ground plane. The DC bias return is

located on common port J1. Constant current sources should supply the DC control currents.

In the low loss state, the series diode must be forward biased and the shunt diode reverse biased. For all

isolated ports, the shunt diode is forward biased while the series diode is reverse biased.

This design improves insertion loss, P1dB, IP3, and switching speed by Incorporating a voltage pull-up resistor

(~100

Ω ) in the DC return path ,J1, under insertion loss Bias. A Typical Value of |-3 V| is achieved at the

Insertion Loss Bias Node using ±20mA, with a Standard , ±5V TTL Controlled PIN Diode Driver.
