Introduction

The F2480 is a 400 to 3000 MHz RF Analog Variable Gain Amplifier (AVGA) that can be used in receivers, transmitters and other applications. Either the amplifier or voltage variable attenuator (VVA) can be configured as the first stage in the cascade. The F2480 RF AVGA provides 12dB typical maximum cascade gain (no attenuation) with 4.3dB noise figure (amplifier as first stage) and 36dB gain adjustment designed to operate with a single +5V supply. Nominally, the amplifier offers +41.50dBm output IP3 using 106mA of ICC. This device is packaged in a 5×5 mm, 32 - pin TQFN with 50Ω single - ended RF input and RF output impedances for ease of integration into the signal - path lineup.
