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.

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.
