Perfectly Synchronised Frequency Structure
The2025MHz-2110MHz/2210MHz-2300MHz Cavity Diplexeroperates the receiving path on a centre frequency of 2067.5 MHz and a pass band of 2025-2110 MHz; and the transmitting path on a centre frequency of 2255 MHz and a passband of 2210-2300MHz. This configuration of the two paths at a separation of 187.5MHz allows for simultaneous transmission and receiving (full duplex operation) with only a very small amount of guard band being wasted therefore
maximising spectral usage (efficiency) in LTE and 5G NR deployments.

Guaranteed Insertion Loss and Flatness

The Cavity Diplexer at Keenlion has a maximum insertion loss of 0.8 dB in both of its passbands. The passband ripple is under 0.6 dB for clean amplitude transmission of the signal. This will allow clean amplitude signal transmission, which will ensure the integrity of the modulation for newer high-order QAM modulation schemes. The units have a VSWR of 1.3:1 or better this produces a small amount of return loss

Multi-Band Rejection Protection

The 2025MHz-2110MHz/2210MHz-2300MHz Cavity Diplexer is characterized by highly out-of-band rejecting capabilities. Adjacent channels provide a minimum of 88 dBc of isolation between the transmitting and receiving paths. The main GNSS frequency bands are protected through 40 dBc minimum rejection at (1559-1602 MHz (GPS L1)), 50 dBc minimum rejection at (1610-1623 MHz GLONASS), and 45 dBc minimum rejection at (1207-1278 MHz GPS L2)). In the case of the co-existence between Bluetooth and WiFi, it offers a 50dBc minimum rejection at 2482-2500 MHz.

Harmonic Suppression, Handling Power

In a Cavity Diplexer, having a Second Harmonic Suppression of 70 dBc and a Third Harmonic Suppression of 50 dBc will reduce the amount of interference that is being produced towards other users of the spectrum. The 400 watt continuous wave rating allows for the use of high power macro base station transmitters without experiencing thermal degradation. The N-type connectors (female antenna port, male transmit/receive ports) provide a robust, weatherproof connection to standard cellular type feeder cables.

Sustainability of the Environment

Cavity Diplexer (2025MHz-2110MHz/2210MHz-2300MHz)is designed to work at extreme temperatures from -45°C up to +85°C and surpasses conventional industrial standards in terms of performance. The original aluminium surface finish will provide long-lasting, corrosion-resistant protection without creating additional coating complexity. Stable thermal and mechanical conditions allow for a steady electrical performance regardless of where they are used – from the desert to arctic facilities.

Si Chuan Keenlion Microwave a large selection in narrowband and broadband configurations, covering frequencies from 0.5 to 50 GHz. They are designed to handle from 10 to 30 watts input power in a 50-ohm transmission system. Microstrip or stripline designs are utilized, and optimized for best performance.
