P/N 63491A-1

Details

P/N 63491A-1 is a double diplexer, for GPS application. The filter passes only the GPS L1 and L2 channels, rejecting everything else, to at least 10 GHz. An evanescent mode structure, the 63491A-1 is truly GPS "state-of-the art".

Channel L2:

• Minimum -3 dBc passband: 1202.6 to 1252.6 MHz
• Maximum loss at 1227.6 +/- 10 MHz: 2 dB
• Phase linearity at 1227.6 +/- 10 MHz: 6 deg. maximum
• Maximum passband VSWR: 1.5:1 (50 ohms)
• Minimum -60 dB rejection: 1047.6 MHz
• Minimum -40 dB rejection: 1347.6 MHz
• Operating power level: at least 0.25 W

Channel L1:

• Minimum -3 dBc passband: 1550.4 to 1600.4 MHz
• Maximum loss at 1575.4 +/- 10 MHz: 2 dB
• Phase linearity at 1575.4 +/- 10 MHz: 6 deg. maximum
• Maximum passband VSWR: 1.5:1 (50 ohms)
• Minimum -60 dB rejection: 1775.4 MHz
• Minimum -40 dB rejection: 1455.4 MHz
• Operating power level: at least 0.25 W

* Maximum group delay difference at L1 and L2 center frequencies: 5 ns
