Parameters

• Frequency range DC to 70 MHz
• Power rating DC to 30 MHz
  • 3 kW continue wave
  • 4 kW PEP (SWR < 1:1.7) - tested with OM-4000
  • Power rating 2 kW @ 50 MHZ, 1 kW @ 70 MHz
• High isolation between A and B ports: 100 dB (20 m), >90 dB (10 m) - no port selected
• High isolation A-1 and B-2: >100 dB (80 m), >84 dB (20 m), > 80 dB (10 m), 75 dB (6 m), 72 dB (4 m)
• High isolation A-1 and B-6: >100 dB (80 m), >84 dB (20 m), > 83 dB (10 m), 82 dB (6 m), 80 dB (4 m)
• Insertion loss better than 0.04 dB (10 m), 0.02 dB (20 m)
• Control DC 2 x 6 wires + 12 to 15 V or image
• Control BCD + 3 to 15 V (TTL compatible or direct 13 to 15 V BCD) image
• When the BCD voltage is higher than 13 V, it directly supplies the relay
• BCD inputs with optocouplers and protections
• BCD inputs wide range 3 to 15 V DC
• BCD data format is 1 to 6
• BCD inputs with positive control compatible with OM-power, Microham. Pull up for open collector - image
• DC supply voltage is recommended 13.8 V
• DC supply current up to 0.4 A
• Fan with lower speed
• Dust filters

Isolation example

• TRX A output power 1 kW =1,341 k 60 dBm
• Isolation to port B is 80 dB → 60 dM - 80 dB = -20 dB
• ~10 UW at TRX port B

⚠ DO NOT forget to

• Isolation between antennas!
• The safe power isolation is not only about the switch isolation!
• Never switch relay during TX!
• Use high quality RF connectors and coax cables. The shielding of coaxial cables has a significant impact on insulation and potential interference.

Connection

• You can use 2 x 6 + GND = 13 wires (12 to 15 V DC)
• You can use 2 x BCD (TTL) + GND + 13.8 V = 8 wires
• You can use 2 x BCD (> 13 V) + GND = 7 wires
• Combination: one port 6 wires, second BCD
