DCS-band 4W HBT Amplifier Module
Product Features
Product Description
Functional Diagram
• 1705 – 1790 MHz
• 31.5 dB Gain
• +25 dBm CDMA2k 7fa Power
(-63 dBc ACPR)
• +12 V Single Supply
The AP504 is a high dynamic range power amplifier in a
RoHS-compliant flange-mount package. The multi-stage
amplifier module has 31.5 dB gain. The module has been
internally optimized for linearity to provide +25 dBm (-63
dBc ACPR) linear power for 7-carrier CDMA2000
applications.
• Power Down Mode
• Bias Current Adjustable
• RoHS-compliant flange-mount pkg
Applications
• Final stage amplifiers for Repeaters
• Optimized for driver amplifier PA
mobile infrastructure
The AP504 uses a high reliability InGaP/GaAs HBT
process technology and does not require any external
matching components. The module operates off of a +12V
supply and does not requiring any negative biasing voltages;
an internal active bias allows the amplifier to maintain high
linearity over temperature. It has the added feature of a
+5V power down control pin. While the module has been
tuned for optimal performance for Class AB applications,
the quiescent current can also be adjusted for Class B
applications through an external resistor. 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 AP504 is targeted for use as a driver or final stage
amplifier in wireless infrastructure where high linearity and
high power is required. This combination makes the device
an excellent candidate for next generation multi-carrier 3G
base stations using the DCS1800 frequency band.
