Functional Diagram
GND
The EC1089 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT is
able to achieve high performance across a broad range with
+41 dBm OIP3 and +24 dBm of compressed 1dB power. It
is housed in an industry standard lead-free/green/RoHS-
compliant SOT-89 package. All devices are 100% RF and
DC tested.

The EC1089 is targeted for use as a driver amplifier in
wireless infrastructure where high linearity and medium
power is required. An internal active bias allows the
EC1089 to maintain high linearity over temperature and
operate directly off a single +5 V supply. This combination
makes the device an excellent candidate for transceiver line
cards in current and next generation multi-carrier 3G base
stations.
