3.2.1.3 IF IN Connector (J3)
The IF IN connector (J3) is a Type N, female connector used to connect the IF at 70 MHz
(140 MHz optional) at –25 to – 45 dBm from the modem to the converter unit. Either
50
Ω or 75Ω cables may be used to connect to J3.
3.2.1.4 IF OUT Connector (J4)
The IF OUT connector (J4) is a Type N, female connector used to connect the IF at
70 MHz (140 MHz optional) from the converter unit to the modem. Either 50
Ω or 75Ω
cables may be used to connect to J4.
3.2.1.5 RX MON Connector (J5)
The RX Mon (J5) connector provides the received (downlink) signal at L-Band (950 to
1700 MHz) for monitoring. This signal has a gain of 20 dB relative to the carrier. J5 is a
Type N, female connector. Nominal output impedance is 50
Ω.
