SONY SGM2014AM

SGM2014AM
GaAs N-channel Dual Gate MES FET
For the availability of this product, please contact the sales office.
Description
The SGM2014AM is an N-channel dual gate GaAs
MES FET for UHF band low-noise amplification.
This FET is suitable for a wide range of applications
including TV tuners, cellular radios, and DBS IF
amplifiers.
Features
• Low voltage operation
• Low noise: NF = 1.5dB (typ.) at 900MHz
• High gain: Ga = 18dB (typ.) at 900MHz
• Low cross-modulation
• High stability
• Built-in gate-protection diode
Application
UHF band amplifier, mixer and oscillator
