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 = 25C, 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.)

Notes:
The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a particular frequency,
it is expected that actual gain will be higher, up to the maximum stable gain. The maximum stable gain is shown in the dashed red line.
The impedance loss plots are shown from 0.05 5.05 GHz, with markers placed in 0.5 GHz increments.

Notes:
1. The thermal resistance is referenced from the junction-

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,
450 mA at an 85

MTTF of 1 million hours is achieved for junction
temperatures below 247
C.
Product Marking
The component will be marked with an

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
