Product Detail

Product Tags

Separate low‑band and high‑band signals cleanly with the Cavity Diplexer from Keenlion. This Cavity Diplexer splits 1350‑1518MHz (LTE) and 1755‑1850MHz (PCS/AWS) with ≤0.7dB insertion loss and deep harmonic suppression. As a B2B factory, we customize every Cavity Diplexer to your system requirements.

Key Features and Manufacturing Strengths

Full Customization: Modify frequency bands, power levels, and connector configurations for regional requirements
Deep Inter-Band Isolation: 90 dBc rejection between 1350-1518 MHz and 1755-1850 MHz paths
Low Insertion Loss: 0.7 dB (max) which save link budgets for long haul applications
GNSS Protection: 45 dBc rejection at 1578 MHz to protect GPS L1 from becoming desensitized
Direct Factory Pricing: Remove distributor margins on custom Cavity Diplexer orders
Technical Support: Engineering team available for system integration consultation

Harmonic Management for Dense Sites

The second and third harmonics of this diplexer are suppressed at 70 and 50 dBc respectively. Therefore, the second and third order intermodulation products created by the transmitter would not be able to produce interference with co-located equipment. The 50 dBc suppression level at 3840 MHz and 5000 MHz will address the increasing issues with Ultra-Wideband and WiFi 6E coexistence that are now being seen at more shared infrastructure locations.

Mechanical Reliability for Global Deployment

Internal silver plating ensures stable electrical performance across -45°C to +85°C operating range. SMA-K connectors with included glass bead transitions accommodate standard semi-rigid cable assemblies. Aluminum construction with original finish withstands coastal and desert environments without coating degradation. Dimensional tolerance ±0.5 mm guarantees mechanical interchangeability in field replacements.
