The ECP052D 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 ECP052D 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
ECP052D 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.

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 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.)
