Description

MMDS Down Converter 2200–2300 MHz

The MK-353 series MMDS down converter is designed for reliable reception of television signals in the 2200–2300 MHz frequency band. Originally developed for MMDS cable television distribution systems, it is also suitable for a wide range of microwave signal conversion applications where low noise and high signal quality are required.

The converter incorporates a high-selectivity input band-pass filter that effectively suppresses out-of-band interference and helps maintain excellent reception even in demanding RF environments. Frequency conversion is performed using a carefully designed local oscillator with low phase noise and good frequency stability, ensuring reliable demodulation of modern digital transmission standards.

Its low phase noise characteristics make the converter suitable for reception of OFDM, QAM, and other digitally modulated signals used in broadband wireless and television distribution systems. The stable conversion process minimizes constellation degradation and helps maintain a low bit error rate.

The rugged aluminium enclosure provides reliable long-term operation in professional installations. The converter is intended primarily for television reception systems but can also be integrated into various microwave receiving systems operating in the 2.2–2.3 GHz band.

Typical applications

MMDS television reception systems
Broadband wireless television distribution
