Crescend Power Amplifiers P10-1FA4-C5-001 User’s Manual
1. General Information.
The power amplifier (PA) is nonlinear AB to C class unit that is intended for frequency (phase)
modulated (manipulated) signals amplification.
There is the fan for forced cooling. The automatic power control loop keeps the output power at the
rated level. It reduces this level, when the load VSWR is above 2, when the heatsink temperature
exceeds +85ºC or under the outer control.

2. Installation Guide.
Unit is intended for a rack installation in a standard 19” cabinet, where it requires 4U high slot. The
installation shall provide a proper air access to the unit; no obstacle for air is allowed closer than 3”
from fan and air exits.
Copper wires # 10 AWG shall be use in DC power line. Wires shall be crimped to ring terminals
3. Operation Guide
- The power supply voltage should be in the limits 46.5 – 49.5 V;
- Do not apply RF signal out of rated 220-222 MHz frequency range:
- For transmitting the input RF power should be in the range 1…4 W.
- Do not destroy the sealing and other labels.
Green LED “DC ON” shines, if the power supply voltage is applied to the unit.
The fan rotates, when the rated RF signal is present at the input.
Red LED “LOW OUT” goes on, if the output power fails to more than 1 dB below the rated level.
It may indicate a problem inside the unit. Be sure that the power supply voltage and input power are
in the allowed limits.
Red LED “HIGH VSWR” goes on, when the load VSWR is greater than 2 – 2.5.
Red LED “HIGH TEMP” goes on, when the heatsink temperature exceeds +85ºC.
FCC RF Exposure:
This transmitter must be restricted to work related operations in a controlled RF exposure
environment. All qualified end-users of this device must have the knowledge to control their
exposure conditions and/or duration, and the exposure conditions and/or duration of their
passengers, to comply with the General Population/Uncontrolled MPE limit and requirements. All
users should maintain a safe distance of 56cm.
Part 90 Signal Booster This is a 90.219 Class B Device
WARNING: This is NOT a CONSUMER device. It is resigned for installation by FCC
LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCCLICENSE or express
consent of an FCC Lincesee to operate this device. You MUST register Part 90 Class AB signal
boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-boosters/registration.
Unauthorized use may result in significant forfeiture penalties, including in excess of $100,000 for
each continuing violation
The output power of this device is limited to 100 Watts. When you choose an antenna to use,
please reduce the maximum output power of this device so that the ERP does not exceed the
5 Watt Limit. To comply with the rule part 90.219: the antenna must have maximum
(-13dBi) gain and the antenna must be installed less than 300m height per FCC Part 90.729
(a) the “ERP vs Antenna Height Table”.
ISED WARNING STATEMENTS
