Note 3:
The 0 dBm0 level for the filter is assumed to be 1.54 Vrms measured at the output of the XMT or RCV filter.
Note 4:
The 0 dBm0 level for the power amplifiers is load dependent. For R

Note:
In the configuration shown, the receive filter power amplifiers will drive a 600

T to R termination to a maximum signal level of 8.5 dBm. An alternative
arrangement, using a transformer winding ratio equivalent to 1.414:1 and 300
X
resistor, R
S
, will provide a maximum signal level of 10.1 dBm across a 600
X
termination impedance.
