Product Information
Product Description
Functional Diagram
The ECM168 is a high performance PAS Amplifier
Module offering excellent linearity. The internally
matched multi-stage amplifier has 33.5 dB gain while
achieving +34 dBm linear output power to meet PHS’s
stringent ACLR requirements.
The ECM168 uses a high reliability InGaP/GaAs HBT
process technology and does not require any external
matching components. The module has an added benefit
by not require any negative biasing voltages; an internal
active bias allows the ECM168 to maintain high linearity
over temperature and operate directly off a single +10V
supply. A low-cost metal housing allows the device to
have a low thermal resistance and achieves over 100
years MTTF. All devices are 100% RF and DC tested.

The ECM168 is targeted for use as a driver amplifier in
wireless infrastructure where high linearity and high
power is required. This combination makes the device an
excellent candidate for next generation PAS base
stations.

Test Conditions
Pout = +34 dBm, Vd = 10V
Pout = +34 dBm, Vd = 10V, See note 2
Pout = +33.5dBm, Vd = 10V
Pout = +34 dBm, Vd = 10V
Pout = +34 dBm, Vd = 10V
Pout = +34 dBm, Vd = 10V
Pout = +34 dBm, Vd = 10V
Pout = +34 dBm, Vd = 10V
1. Test conditions unless otherwise noted: 25 ºC, Supply Voltage = +10 V, Output Power = +34 dBm, RF signal modulation is per PHS RCR-28.
2. The actual test limits performed by WJ correspond to an internal maximum ACLR specification of -65 dBc at +34 dBm output power.

Notes:
1. Please note that for reliable operation, the evaluation board will
have to be mounted to a much larger heat sink during operation
and in laboratory environments to dissipate the power consumed
by the device. The use of a convection fan is also recommended
in laboratory environments.
2. The area around the module underneath the PCB should not
contain any soldermask in order to maintain good RF grounding.
