Product Description
The ECP103 is a high dynamic range driver amplifier in
a low-cost surface mount package. The InGaP/GaAs
HBT is able to achieve superior performance for various
narrowband-tuned application circuits with up to +46
dBm OIP3 and +30.5 dBm of compressed 1-dB power.
The part is housed in an industry standard SOIC-8 SMT
package. All devices are 100% RF and DC tested.
The ECP103 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
ECP103 to maintain high linearity over temperature and
operate directly off a single +5V supply.
This
combination makes the device an excellent candidate for
driver amplifier stages in wireless-LAN, digital
multimedia broadcast, or fixed wireless applications. The
device can also be used in next generation RFID readers.

1. Test conditions unless otherwise noted: T = 25ºC, Vsupply = +5 V in a tuned application circuit.
2. 3OIP measured with two tones at an output power of +15 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 90 mA at P1dB. Pin 1
is used as a reference voltage for the internal biasing circuitry. It is expected that Pin 1 will pull
10.8 mA of current when used with a series bias resistor of R1=51 . (ie. total device current
typically will be 461 mA.)
