Receiver including FET frequency mixer |
摘要 |
A receiver including an FET frequency mixer is disclosed. A local oscillator generates a local oscillator signal which is applied to a first amplifier whose gain is varied as a function of a control signal applied thereto. The output of the first amplifier is applied to a first gate electrode of the FET frequency mixer. A high-frequency signal received by the receiver is applied to a second amplifier whose gain is also controlled by the control signal. The output of the second amplifier is applied to a second gate electrode of the FET frequency mixer. The control signal is generated as a function of the output of the FET mixer.
