2.1.1.2 TX/RF Output (J2)
The TX/RF output is a type N connector that sends the signal to the antenna. The output
impedance is 50
!. The output frequency range is from 5.845 to 6.425 GHz. The output
1 dB compression point is +8 dBm.
2.1.1.3 RX/IF Output (J3)
The RX/IF output is a TNC connector that sends the received signal to the indoor unit.
The output impedance is 50
!, and the frequency is 70 " 18 MHz (optional 140
" 36 MHz).
The 1 dB output compression point is +15 dBm. Maximum output power operation is
+9 dBm (-6 dB from 1 dB compression) to -50 dBm, depending on system gain
requirements. The down converter has 26 to 47 dB of gain, and is adjustable by the
customer from 0 to 21 dB of attenuation.
The typical system gain includes a 50 dB LNA, making the total system gain 76 to
97 dB.
Note: A 60 dB LNA is used only when there are extremely long cables from the LNA to
the down converter and can be ordered as an option.
2.1.1.4 RX/RF Input (J4)
The RX/RF input is a type N connector that receives the signal from the LNA. The input
impedance is 50
!. The input frequency range is from 3.620 to 4.200 GHz. The input
signal level ranges between -50 and -25 dBm, depending on LNA and antenna gain.
The input level should be set to give the required signal level at J3, the RX/IF Output.
