Product Information
Product Features
Product Description
Functional Diagram
The ECP050D 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 in a lead-free/
green/RoHS-compliant 16-pin 4x4mm QFN surface-
mount package. All devices are 100% RF and DC tested.

The ECP050D 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
ECP050D to maintain high linearity over temperature and

4. Typical parameters reflect performance in a tuned application circuit at +25 C.
1. Test conditions unless otherwise noted. 25 ºC, 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. It is
expected that the current can increase up to 300mA at P1dB.
