AC Electrical Characteristics
Unless otherwise specified T
assumed to be 1 54 Vrms measured at the output of the transmit or receive filter Limits printed in BOLD characters are
guaranteed for V
25 C All other limits are assured by correlation with other production tests and or product design and characterization Typicals
specified at V
Note 1 Maximum power consumption will depend on the load impedance connected to the power amplifier This specification listed assumes 0 dBm is delivered to
600X connected from PWRO
Note 2 Voltage input to receive filter at 0V VF
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 6 Previous revisions of the datasheet did not clearly indicate this specification requires power amps in powerdown (PWRI
Typical Application
Note 1 Transmit voltage gain
Note 2 Receive gain
Note In the configuration shown the receive filter power amplifiers will drive a 600X 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 300X resistor R
