BF1207

Features:

Two low noise gain controlled amplifiers in a single package. One with a fully integrated bias and one with partly integrated bias
Internal switch to save external components
Superior cross-modulation performance during AGC
High forward transfer admittance
High forward transfer admittance to input capacitance ratio


Application

Gain controlled low noise amplifiers for Very High Frequency (VHF) and Ultra High Frequency (UHF) applications with 5 V supply voltage, such as digital and analog television tuners and professional communication equipment


Pinout




Description

The BF1207 is a combination of two dual gate MOSFET amplifiers with shared source and gate2 leads and an integrated switch.
The source and substrate are interconnected. Internal bias circuits enable Direct Current (DC) stabilization and a very good cross-modulation performance during Automatic Gain Control (AGC). Integrated diodes between the gates and source protect against excessive input voltage surges. The BF1207 has a SOT363 micro-miniature plastic package.
