PRO-PHY85-3

3-Channel Hybrid Combiner for 85 MHz Transmitters

DESCRIPTION

Combining three transmitters or receivers on the same antenna.

Better utilization of good antenna position.

Three antennas on the same transmitter or receiver.

The only combining option with very small TX-TX frequency spacing.

60 W load supplied (other loads or no load as option).

SPECIFICATIONS

ELECTRICAL

FILTER TYPE Hybrid Junction

FREQUENCY 68 - 88 MHz (see table)

MAX. INPUT POWER

75 W per channel

(max. 150 W with larger load)

INSERTION LOSS

< 5.2 dB ± 0.3 dB @ 2 MHz BW

< 5.4 dB ± 0.3 dB @ 4 MHz BW

ISOLATION TX 1-TX 2

(*see note)

> 26 dB @ 2 MHz BW

> 25 dB @ 4 MHz BW

IMPEDANCE Nom. 50 Ω

LOAD (**see note) 60 W load fitted (other ratings available)

SWR < 1.5 with all other ports terminated with 50 Ω

MECHANICAL

TEMP. RANGE –30° C → +60° C

CONNECTORS N-female (other types available)

DIMENSIONS (L x W x H) 400 x 89(incl. conn.) x 42 mm (excl. loads)

WEIGHT Approx. 1300 g (excl. load)

* The isolation between the TX ports is directly dependent on the

terminating SWR on the antenna port. With an antenna load SWR = 1.5, the

isolation between the two TX ports will be reduced to 20 dB @ 5 MHz

bandwidth.

** The SWR of the load´s should be < 1.1! Each load should be able to

dissipate 2/3 of the input power.

E.g.: With 50 W input, each load should be able to dissipate 50 W x 2/3 =

33 W.
