Overview
Description
The F1451 is a High-Gain/High-Linearity 450MHz to 1100MHz TX Variable Gain Amplifier used in transmitter applications. The F1451 TX VGA provides 32dB maximum gain with +41dBm OIP3 and 3.6dB noise figure. Up to 29.5dB gain control is achieved using the combination of a digital step attenuator (DSA) plus KLIN™ RF variable gain amplifier gain adjustment. This device uses a single 5V supply and 185mA of ICC. This device is packaged in a 6 × 6 mm, 28-QFN with 50Ω single-ended RF input and RF output impedances for ease of integration into the signal path.

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.
