Product Information
Product Features
Product Description
Functional Diagram
The ECP052 is a high dynamic range driver amplifier in
a low-cost surface mount package. The InGaP/GaAs
HBT is able to achieve high performance for various
narrowband-tuned application circuits with up to +44
dBm OIP3 and +28.5 dBm of compressed 1dB power. It
is housed in an industry standard SOIC-8 or 16-pin
4x4mm QFN SMT package. All devices are 100% RF
and DC tested.

ECP052D
The ECP052 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
ECP052 to maintain high linearity over temperature and

1. Test conditions unless otherwise noted: 25ºC, Vsupply = +5 V, in tuned application circuit.
2. 3OIP measured with two tones at an output power of +11 dBm/tone separated by 1 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. This corresponds to the quiescent current or operating current under small-signal conditions into pins 6, 7, and 8. It is expected that the current can increase by an additional 50 mA at P1dB. Pin 1 is used as a
reference voltage for the internal biasing circuitry. It is expected that Pin 1 will pull 12mA of current when used with a series bias resistor of R1=100Ω. (ie. total device current typically will be 262 mA.)
