Range of duplexers & Rx cavity filters cover the tetra bands

Insertion loss is 1.2dB maximum over the full operating temperature range of –40C ~ +70C and 3rd Order IMP is less than –135dBc when measured with 2 x 43dBm tones with 1MHz spacing. Isolation between bands is 80DB min. Rejection is 80dB min and return loss is better than 20dB over the full operating temperature range.
Dimensions are 223 x 168 x 88 mm max over tuning screws, with Type NF connectors on transmit and antenna ports and SMA (F) on the receive port.

The associated RX band filter for this 455~460MHz channel model 85358A, has an upper stopband of 465~1000MHz with 55dB min. rejection and 80dB min at 71.85MHz & [Rx frequency + 143.7MHz]. Dimensions are 166 x 112 x 74 mm.

These devices complement the range of TETRA specific isolators and power amplifiers manufactured by Eleading Technologies. Please contact the following for further information.
