Product Description
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
operate directly off a single +5V supply.
This
combination makes the device an excellent candidate for
transceiver line cards in current and next generation
multi-carrier 3G base stations.

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.
