Preliminary Product Information
Product Description
The FP2189 is a high performance 1-Watt HFET
(Heterostructure FET) in a low-cost SOT-89 surfacemount package. This device works optimally at a drai
ias of +8 V and 250 mA to achieve +45 dBm outpu
IP3 performance and an output power of +31 dBm a
1-dB compression.
The device conforms to WJ Communications’ long
history of producing high reliability and qualit
components. The FP2189 has an associated MTBF o
greater than 100 years at a mounting temperature o
85°C. All devices are 100% RF & DC tested.
The product is targeted for use as driver amplifiers fo
wireless infrastructure where high performance and high
efficiency are required.

2. Pinch-off voltage is measured when Ids = 0.4 mA.
3. Test conditions unless otherwise noted: T = 25ºC, VDS = 8 V, IDQ = 250 mA, frequency = 900 MHz
in an application circuit with ZL = Z
4. 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.
