Description

MES 1000 series Band Pass Duplexers are manufactured by precision milling of Aluminium block. After machining the cavities and lids including resonators made of copper are silver plated.


Typical Tx to Rx frequency Separation are :

9.5 / 14 / 25 MHz in lower bands i.e. 300-470 MHz
45 MHz or more in mid bands i.e. 600 & 900 MHz
61 / 90 / 161 MHz in higher bands i.e. 1.35 GHz upwards


Pass bandwidths typically 2, 3, 5, 8 MHz and higher are custom built as per the frequency band. Low insertion loss and high isolation are guaranteed. Field tuning is accomplished with silver plated tuning screws on the two sides of the Low pass & High pass Filters. The entire unit is given a coat of epoxy paint for additional protection.

Features :
  • Option of wide frequency range 330 MHz -3GHz in different frequency bands.
  • Tunable in entire band
  • Compact & Rugged design for use in Digital Microwaves Radios.
  • Extreme temperature working conditions - 30 to + 60 deg C
  • Excellent Electrical characteristics.
  • Choice of connectors BNC, SMA, TNC, N, UHF

Application :

These Duplexers are most commonly deployed as internal units suitably adapter for plug into Digital Microwave Radio terminals operating upto 25 Watts.
