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.
