Product Description
The EC1089 is a high dynamic range driver amplifier in a
low-cost surface mount package. The InGaP/GaAs HBT is
able to achieve high performance across a broad range with
+41 dBm OIP3 and +24 dBm of compressed 1dB power. It
is housed in an industry standard lead-free/green/RoHS-
compliant SOT-89 package. All devices are 100% RF and
DC tested.
The EC1089 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
EC1089 to maintain high linearity over temperature and
operate directly off a single +5 V supply. This combination
makes the device an excellent candidate for transceiver line
cards in current and next generation multi-carrier 3G base
stations.

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 plots are shown from 50 – 3000 MHz, with markers placed at 0.5 – 3.0 GHz in 0.5 GHz increments.

Mounting Config. Notes
1. 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” ).
2. Add as much copper as possible to inner and outer
layers near the part to ensure optimal thermal
performance.
3. 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.
4. Do not put solder mask on the backside of the PC board
in the region where the board contacts the heatsink.
5. RF trace width depends upon the PC board material
and construction.
6. Use 1 oz. Copper minimum.
7. All dimensions are in millimeters (inches). Angles are
in degrees.
