• # 545185 - Type 1A amplifier module with AGC. AGC has 

445.25 MHz pilot frequency and manual temperature backoff 
control. 

Note: Amplifier module also comes configured with reverse
amplifier, reverse combiner, 16.5 dB interstage EQ, interstage
pad, output pads, 0 dB reverse output EQ, 40/51 diplex filters,
and integrated power supply. Power supply has 30 V AC

Coated 4-port housing with external test point 
access

• Plug-in Pads (attenuators): 

– 1 required for forward (1 input)
– 4 required for reverse (3 inputs, 1 output)
– 1 required for AGC only if Main output level at pilot 

frequency is NOT 33 dBmV (AGC comes configured 
with a 9 dB pad, which is appropriate for 33 dBmV Main 
output level at pilot frequency).

Available in 0.5 dB steps from 0 to 20 dB. Order Model PP-* 
(* denotes pad value), specify value. 

• Plug-in Forward Input Equalizer, 1 required. Available in 1.5 dB 

steps from 0 to 28.5 dB at 750 MHz. Order Model EQ750-*

Model EQ40S-* (* denotes equalizer value), specify value.

• #467351 230 V AC Surge Protector
• Plug-in Cable Simulator. Simulates cable losses, creating tilt 

opposite that of Equalizers. Use in place of Forward Input 
Equalizer as needed to maintain proper output tilt in short 
spaced locations. Available in 1.5 dB steps from 1.5 dB to 
12.0 dB cable loss at 750 MHz.
