What is a cavity diplexer?
a cavity diplexer is a passive device that allows simultaneous transmission and reception of signals over a single antenna by separating designated frequency bands. our 891-903mhz/936-948mhz cavity diplexer is engineered to provide exceptional isolation between the rx (891-903mhz) and tx (936-948mhz) bands.

Key technical features
our cavity diplexer is designed to meet the demanding requirements of Modern communication systems:
• rx center frequency: 897mhz ±1mhz
• tx center frequency: 942mhz ±1mhz
• insertion loss: ≤1db across both bands
• voltage standing wave ratio (vswr): ≤1.3:1
• rejection: ≥65db between bands
• impedance: 50 ohms
• connectors: sma-female on all ports
• operating power: 10w forward, 2w reverse
• operating temperature: -20°c to +65°c
• material: aluminum with black paint finish

What sets our cavity diplexer apart?
• precision manufacturing: our 20-year factory in chengdu produces each diplexer with rigorous quality control.
• made-to-order customization: we offer frequency adjustments, connector changes, and custom mounting brackets.
• rapid delivery: samples ship within 48 hours, with standard orders fulfilled in 21 days.
