DESCRIPTION
The TC1201 is a GaAs Pseudomorphic High Electron Mobility Transistor (PHEMT) chip, which has very low
noise figure, high associated gain and high dynamic range. The device can be used in circuits up to 30 GHz and
suitable for low noise and medium power amplifier applications including a wide range of commercial and
military applications. All devices are 100% DC tested to assure consistent quality. All bond pads are gold plated
for either thermo-compression or thermo-sonic wire bonding.

Note:
* For the tight control of the pinch-off voltage . TC1201’s are divided into 3 groups:
(1)
TC1201P0710
: Vp = -0.7V to -1.0V (2)
TC1201P0811
: Vp = -0.8V to -1.1V (3)
TC1201P0912
: Vp = -0.9V to -1.2V
In addition, the customers may specify their requirements.
