Description

AKON’s A20-MH260 is a 0.8 to 20.0 GHz microwave tuner of the classical type. It features a 60 dB dynamic range expander, an integrated input switch/limiter and launches through the LNA.  The unit features an 8-channel filter bank preselector which eliminates received image frequencies. The unit features dual conversion steps to a final IF output frequency of 1 GHz. Output bandwidth is also selectable between 550 and 50 MHz. Conversion gain is 5 dB, Dynamic range extends to -70 dBm, of which the first 50 dB is spurious-free. LO sources are externally applied.
