N-channel dual-gate PoLo MOS-FETs
FEATURES
• Short channel transistor with high
forwardtransferadmittancetoinput
capacitance ratio
• Low noise gain controlled amplifier
• Partly internal self-biasing circuit to
ensure good cross-modulation
performanceduring AGC andgood
DC stabilization.
APPLICATIONS
• VHF and UHF applications with
3 to 9 V supply voltage, such as
digital and analogue television
tuners and professional
communications equipment.
