Abstract:
A variable gain amplifier circuit including a first amplifier, a second amplifier, and a variable capacitor connected in series between the first amplifier and the second amplifier is disclosed. As a gain of the variable gain amplifier circuit varies, the input impedance, output impedance, noise figure and third-order output intercept point (OIP3) of the variable gain amplifier circuit remain unchanged.

Claim (Index 1):
A variable gain amplifier circuit comprising:\n a first amplifier; a second amplifier; a variable capacitor connected in series between the first amplifier and the second amplifier; a shunt feedback resistor; and an emitter degeneration resistor, wherein the shunt feedback resistor and the emitter degeneration resistor set at least one of an input impedance and a gain of the first amplifier.
