P/N 91122A-1

P/N 91122A-1 is a right-angle transition version of the 60661A-3 JTIDS/MIDS high power bandpass filter.  This unique drop-in device incorporates our traditional high power evanescent mode bandpass design with an additional coaxial notch at 944 MHz to ensure compliance with demanding CS04 test requirements. The filter is as small as can be when considering the combination of high power performance and low insertion loss. The unit is gold flashed for materials compatability in drop-in applications.

Max. passband loss                                                   0.8 dB (0.6 dB typical)

Max. passband delay variation                 ± 2.75 ns PTP (± 2 ns from 969-1206 MHz)

Min. rejection at 944 MHz                                                    8 dBc

Min. rejection at 900 MHz                                                  19 dBc

Min. rejection at 1250 MHz                                              5.5 dBc

Min. rejection at 1295 MHz                                               25 dBc

Filter response                                  Monotonic within 2 dB down to 900 MHz, except in the immediate vicinity of the                                                                       notch at 944 MHz.

Passband power                                                300 W pk,  22% duty long term,  36% short term
