Product Description
Functional Diagram
GND
The ECG012 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 +36 dBm OIP3 and +20 dBm of compressed
1dB power. It is housed in a lead-free/green/RoHS-
compliant SOT-89 SMT package. All devices are 100%
RF and DC tested.

The ECG012 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
ECG012 to maintain high linearity over temperature and
operate directly off a single +3 V supply. This
combination makes the device an excellent candidate for
transceiver line cards in current and next generation
multi-carrier 3G base stations.

2. 3OIP measured with two tones at an output power of +6 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
