product specifications for demanding rf environments brickwall series integrated mmds downconverters n ow mmds system designers and engineers can improve system performance with a product designed to operate in the most demanding of rf environments, while also protecting the lna from the inevitable introduction of new interfering services. the brickwall series of mmds downconverters uses a ?ilter first approach for pre-lna brickwall protection against pcs, wcs, and radar services. unwanted interfering carriers are filtered out before they reach the first amplifier stage in the circuit, preventing the amplifier from being overdriven and allowing use in areas previously not available. the hi_q interdigital style filter offers superior discrimination at the lowest insertion loss. brickwall series integrated mmds downconverters are directly matched to an antenna, allowing full rf integration. the antennas are either andrew corporation s mag grid or microceptor series of s-band products. the downconverters are compatible to multiple modulation schemes, including 256 qam, and are available in a variety of amplifier gains. 26t-5446 qd-5446 ordering information type # antenna type bandpass filter radar notch amp gain dl-5447 13 dbi dual microceptor pre-lna brickwall 20 db dl-5446 13 dbi dual microceptor pre-lna brickwall 32 db dl-5445 13 dbi dual microceptor pre-lna brickwall 36 db QD-5447 16 dbi quad microceptor pre-lna brickwall 20 db qd-5446 16 dbi quad microceptor pre-lna brickwall 32 db qd-5445 16 dbi quad microceptor pre-lna brickwall 36 db dl-5453 13 dbi dual microceptor pre-lna brickwall x 20 db dl-5451 13 dbi dual microceptor pre-lna brickwall x 32 db dl-5450 13 dbi dual microceptor pre-lna brickwall x 36 db qd-5453 16 dbi quad microceptor pre-lna brickwall x 20 db qd-5451 16 dbi quad microceptor pre-lna brickwall x 32 db qd-5450 16 dbi quad microceptor pre-lna brickwall x 36 db 18t-5447 18 dbi mag grid parabolic pre-lna brickwall 20 db 18t-5446 18 dbi mag grid parabolic pre-lna brickwall 32 db 18t-5445 18 dbi mag grid parabolic pre-lna brickwall 36 db 26t-5447 24 dbi mag grid parabolic pre-lna brickwall 20 db 26t-5446 24 dbi mag grid parabolic pre-lna brickwall 32 db 26t-5445 24 dbi mag grid parabolic pre-lna brickwall 36 db features and options pre-lna filtering lowest insertion loss digital compatibility low noise figure superior discrimination
