hello
I'm Alber as a FAE in Arrow Korea.
Generally, TRF370315(or TRF370333) used to as up-converting device from IF(or Baseband) to RF.
But, my customer asked about this device to use for control RF phase and Gain.
following the example
1. the modulated RF signal(WCDMA or LTE) take in the LO port.
2. DC voltage take in the BBi and BBq port and they can control this voltage level.
then, can they control the phase(or gain) of output signal?
if it's possible, can they generate 90 degree(or they wanted degree) shifted signal at output port?
