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

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.
Typical parameters represent performance in an application circuit.
I
dq
is the quiescent drain current at small signal output levels. The
current may increase as the output power is increased near its
