A HF/VHF Bridge ... with the ETC1-1-13TR
SWR Measurement • Return Loss Bridge, 5 MHz ... 3 GHz
✈ Circuit Description
For maximum Flexibility, the case has 4 x SMA Connectors to allow for any HF Source, Load, Reference or Measurement Device (Powermeter, Spectrum Analyzer, ...) to be connected. R1 and R2 are 49.9 Ω, 1206, 0.1%, 25ppm (RG3216P-49R9-B-T5).
The ETC1-1-13TR is from MACOM.
✈ Performance
Insertion Loss (SRC - MEAS) is -12 dB @ 20 MHz when a Short is connected.
Changing to a Load, the level will drop by an additional 32 dB. This is also called Directivity or sometimes Isolation.
