AFE7422EVM: EVM - Component Replacement

Part Number: AFE7422EVM
Other Parts Discussed in Thread: AFE7422

Dear Vijay/Team,

Based on AFE7422 Schematic, the BALUN in Transmit and Receive path were listed below,

Component Frequency Range
Min (MHZ)
Frequency Range
Max (MHZ)
Receive Path TCM2-672X+ 1700 6700
Transmit Path TCM3-452X-1+ 20 4000

Our targeted Frequency of operation is VHF Band.

It is recommended to change the Receive BALUN  ?

If so, Can you please suggest us the exact part which can be replaced with RX BALUN (TCM2-672X+)?

  • For lower frequency bands we have used: Mini-Circuits TCM2-43X+.  This transformer's published range is 10 MHz to 4000 MHz.  It is the same package style as the '672X but in a different pin-out configuration.
