APPENDIX G: EXAMPLES OF DUPLEXER DATA

On the following pages are isolation and insertion loss characteristics for a variety of duplexers.

The 150 MHz duplexer exhibits 70 dB isolation with 1.5 dB insertion loss at a minimum frequency

separation of 500 KHz. Isolation and insertion loss ﬁ gures would improve greatly with larger separations.

Isolation of 70 dB and an insertion loss of 0.8 dB may be possible at a spacing of 3 MHz.

The 400 MHz duplexer exhibits 75 dB isolation with 0.8 dB insertion loss at a minimum frequency

separation of 5.0 MHz.

The 800 MHz duplexer exhibits 70 dB isolation with 1.0 dB insertion loss at a minimum frequency

separation of 3.6 MHz.
