Preliminary Specification
N-Channel Dual-Gate MOSFET
TMF3202Z
□ Description
The TMF3202Z is an enhancement type N-channel field-effect
transistor. The source and substrate are interconnected. Internal
bias circuits enable DC stabilization and a very good cross-
modulation performance during AGC. Integrated diodes between
the gates and source protect against excessive input voltage
surges. The transistor has a SOT343 micro-miniature plastic
package.
□ Features
- Gain controlled amplifier with AGC
- Integrated gate protection diodes
- High AGC-range, high gain, low noise figure
□ Applications

- Gain controlled input stage for UHF and VHF tuners
- Professional communications equipment
