The FH1 is a high dynamic range FET packaged in a low-
cost surface-mount package. The combination of low noise
figure and high output IP3 at the same bias point makes it
ideal for receiver and transmitter applications. The device
combines dependable performance with superb quality to
maintain MTTF values exceeding 100 years at mounting
temperatures of +85 qC. The FH1 is available the
enviornmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package.
The device utilizes a high reliability GaAs MESFET
technology and is targeted for applications where high
linearity is required. It is well suited for various current
and next generation wireless technologies such as GPRS,
GSM, CDMA, and W-CDMA. In addition, the FH1 will
work for other applications within the 50 to 3000 MHz
frequency range such as fixed wireless.

3. Pinch-off voltage is measured with Ids = 0.6 mA.
4. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
5. The minimum noise figure has £ S = £ L = £ OPT.
