IF and L-band Routing Matrix : QFM 2500
The QFM 2500 16 x 16 IF and L-band (fan-In) combining matrix in a compact 1 RU enclosure. The QFM also features Quintech’s latest
technology, which provides maximum reliability with internal signal path redundancy and auto re-route capabilities. The QFM’s operating frequency range covers 50 MHz to 2150 MHz. It also offers manual and automatic AGC modes with a range of -20dB to +8 dB in 0.5 dB steps. Input signal level balancing for optimal system performance.The front panel LED’s allow monitoring of power supply and alarm status information and can be controlled remotely via web browser.
