FH101
Product Description
The FH101 is a high dynamic range FET packaged
in a low cost surface mount package. The device is
available in both the standard SOT-89 package
and the environmentally friendly lead-free and
"green" SOT-89 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 FH101 achieves +36 dBm OIP3
at a mounting temperature of 85C with an associ-
ated MTBF of >100 years. The package is a SOT-
89. All devices are 100% RF and DC tested.
The product is targeted for applications where high
linearity is required.

Notes:
1. DC and RF parameters measured under the following conditions unless otherwise noted.
25C with Vds = 5.0 V, Vgs = 0 V, test frequency = 800 MHz, 50 W system.
2. OIP3 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 OIP3 using a 2:1 slope rule.
3. Device needs appropriate match to become unconditionally stable.
4. Degradation of OIP3 occurs at low temperatures. Minimum typical OIP3 at -40C is +36 dBm.
5. Idss is measured with Vgs = 0 V.
6. Pinch off voltage is measured when Ids = 0.6 mA.
7. Measured with Vds = 3.3 V, 50% Idss.
