概要
説明
The F1455 is a high-gain/high-linearity 1400MHz to 2300MHz TX variable gain amplifier (VGA) used in transmitter applications. The F1455 TX VGA provides 32dB maximum gain with +39dBm OIP3 and 4dB 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 216mA of ICC. It is packaged in a 6mm x 6mm, 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.
