Parameters
(Downlink & Uplink)
Typical Specifications
Electrical
Available Operating Frequency Bands
Custom build sub-bands between 150-174 MHz
General Duplexer specs:
One window per path (DL & UL), non-interleaved
channel frequencies, minimum 3 MHz separation
between DL & UL frequency band edges, to be
specified upon order.
Downlink Output Power 1dB Compression (P1dB CW)
20 Watt (standard) or 5 Watt.
Low Power option available (+17 dBm for service
fiber DAS)
Downlink Third Order Intercept Point (OIP3), cascaded
system after custom BPF loss.
* Two-tone test, 2W each * 25kHz-1MHz spacing
NOTE: MCPA module OIP3 is +53 dBm (20Watt option)
> +50 dBm
Maximum Recommended Downlink Operating Power
Levels, 10 dB back-off from P1dB (20W).
2 carriers: +30 dBm each; 4 carrier: +27 dBm each
8 carrier: +24 dBm each; 16 carrier: +21 dBm each
Downlink Maximum Gain (net)
60 dB
Downlink maximum input level for normal operation
-20 dBm
Downlink Noise Figure (at system level including
custom BPF loss)
<6 dB
Uplink Output Power 1dB Compression (P1dB CW)
options
20 Watt (standard) or 5 Watt.
Low Power option available (+17 dBm for service
fiber DAS)
Uplink Maximum Operating Output Power Setting
0 dBm (to feed fiber transmitter)
Uplink Maximum Gain (net)
60 dB
Uplink Maximum input level for normal operation
-20 dBm
Uplink Noise Figure (at system level including custom
BPF loss), for low level signal outside of OLC range.
Note: active stages NF is 2 dB typ.
<6 dB
Downlink and Uplink RF Input Limit Control (iALC) range
Activation of the ILC does not create inter-modulation
products or spurious outputs with levels greater than -
60 dBc over the entire range of operation of the ILC,
for any frequency spacing including down to 25 kHz. It
prevents internal saturation of the amplifier stages
> 25 dB (30 dB typ)
Gain Control range (UL & DL)
>25 dB (30 dB typ), 1dB digital step
System Signal Gain Flatness (UL & DL)
±1.5 dB
System Input/Output Interface (UL & DL)
50 Ohm, coaxial Type-N; VSWR 1.5:1 typ
