PRO-PHY450-2

2-Channel Hybrid Ring Combiner for 450 MHz Transmitters

DESCRIPTION

Combining two transmitters or receivers on the same antenna.

Better utilization of good antenna position.

Two antennas on the same transmitter or receiver.

Combining two signal generators.

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 Ring Junction

FREQUENCY 380 - 475 MHz (see table)

MAX. INPUT POWER 50 W per channel

(max. 150 W with larger load)

INSERTION LOSS < 3.4 dB @ 10 MHz BW

< 3.7 dB @ 20 MHz BW

ISOLATION TX 1-TX 2

(*see note)

> 35 dB @ 10 MHz BW

> 30 dB @ 20 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 as option)

DIMENSIONS (L x W x H) 216 x 89 (incl. conn.) x 42 mm (excl. load)

WEIGHT Approx. 700 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 loads should be < 1.1! The load should be able to

dissipate 1/2 of the total input power.

E.g.: With 50 W input in total for the two channels, the load should be able

to dissipate 50 W x 1/2 = 25 W.

TYPICAL RESPONSE CURVE

PROCOM A/S reserve the right to amend specifications

without prior notice.
