Base Station Duplexers

Q-1220E

Designed for the 66-88 MHz band, this 4-cavity duplexer is ideal for system with frequency separations as low as 200 kHz.

Q-2220E

This 4-cavity duplexer exhibits 70 dB isolation and only 1.5 dB insertion loss at its minimum frequency separation of 500 kHz. Isolation and insertion loss figures improve greatly at larger separation. Isolation of 80 dB and insertion loss of 0.8 db is typical at 3 MHz spacing.
