描述
The F2480 is a 400MHz to 3000MHz 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 a 12dB typical maximum cascade gain (no attenuation) with a 4.3dB noise figure (amplifier as first stage) and a 36dB gain adjustment designed to operate with a single +5V supply. Nominally, the Zero-Distortion™ amplifier offers +41.5dBm output IP3 using 106mA of ICC. This device is packaged in a 5mm x 5mm, 32-TQFN with 50Ω single-ended RF input and RF output impedances for ease of integration into the signal-path lineup.

Constant Linearity (KLIN) RF Technology by IDT
IDT’s KLIN (constant linearity) RF technology extends both OIP3 and output 1 dB compression point (P1dBO) amplifier gain settings. This is particularly valuable in transmitter designs where the gain of the device is maintained within a normal gain setting window about 6 dB below maximum gain.
KLIN refers to Constant High Linearity Inner Amplifiers as the gain is adjusted. This technology extends the compression performance over a wide range of input powers, and also extends output third order intercept and corresponding inner modulation distortion performance over a wide range of output powers.
This technology is particularly advantageous in transmitter designs, where the gain of the device is maintained within a normal gain setting window.
This technology applies to some of IDT's high-gain, high-linearity transmitter variable gain amplifiers (VGAs). For more information, visit: http://www.idt.com/products/rf-products/variable-gain-amplifiers-vga.
