Ka-band LNB 25.2-26.2 GHz WR-28 N/F/SMA

The Ka-band LNB 25.2–26.2 GHz WR-28 N/F/SMA is a high-performance downconverter tailored for professional RF systems, satellite communications, and telecommunication diagnostics. This unit supports input frequencies from 25.2 to 26.2 GHz and downconverts signals to a stable IF range of 1.0–2.0 GHz, making it suitable for integration into a wide range of Ka-band equipment.

Thanks to a highly stable 12.1 GHz local oscillator, internal 50 MHz reference generator with ±0.5 ppm frequency instability, and excellent phase noise characteristics (−90 dBc/Hz @1 kHz), this converter ensures superior signal clarity and minimal degradation. With a gain of 51 dB, mirror channel suppression of 42 dB, and output power of 5 dBm (P1dB), it offers excellent linearity and dynamic performance.
