Technical report 009-TR-001

On 9.3 MHz T/R switch

Vyacheslav Volotovskyy and Boguslaw Tomanek

This technical report includes:

 description of the switch (page 2)

schematics of the switch (Fig. 1)

 photo of the switch (Fig. 2)

An active T/R switch is activated through DC line (pin #4 as an active line, pin #12 as a return).

DC voltage of 2.5 V and current of 0.4 A are required to switch the coil from Rx mode into Tx

mode. RF isolation values between Rx and Tx ports are 38 dB in Rx mode and 50 dB in Tx

mode. Through losses are less than 0.1 dB for both transmitter and receiver ports.
