Product Description
The ECP203 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 +48
dBm OIP3 and +32.5 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.
The ECP203 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
ECP203 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: 25C, Vsupply = +5 V in tuned application circuit.
2. 3OIP measured with two tones at an output power of +17 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 200 mA at P1dB. Pin 1 is used as
a reference voltage for the internal biasing circuitry. It is expected that Pin 1 will pull 22mA of current when used with a series bias resistor of R1=15
. (ie. total device current typically will be 822 mA.)

Notes:
1. The thermal resistance is referenced from the junction-
to-case at a case temperature of 85
C. Tjc is a function
of the voltage at pins 6 and 7 and the current applied to
pins 6, 7, and 8 and can be calculated by:
Tjc = Tcase + Rth * Vcc * Icc
2. This corresponds to the typical biasing condition of +5V,
800 mA at an 85
C case temperature. A minimum
MTTF of 1 million hours is achieved for junction
temperatures below 247
C.
Product Marking
The component will be marked with an
"ECP203G" designator with an alphanumeric

Mounting Config. Notes
1. A heatsink underneath the area of the PCB for the mounted
device is strictly required for proper thermal operation.
Damage to the device can occur without the use of one.
2. Ground / thermal vias are critical for the proper performance
of this device. Vias should use a .35mm (#80 / .0135" )
diameter drill and have a final plated thru diameter of .25
mm (.010" ).
3. Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
4. Mounting screws can be added near the part to fasten the
board to a heatsink. Ensure that the ground / thermal via
region contacts the heatsink.
5. Do not put solder mask on the backside of the PC board in
the region where the board contacts the heatsink.
6. RF trace width depends upon the PC board material and
construction.
7. Use 1 oz. Copper minimum.
