Alpha Delta DELTA-4B/N

4-Way Coaxial Switch (1500 Watt CW)

height=

The excellent quality of this part is characterized by a fusion with a constant impedance microstrip cavity for UHF. No leaky wafer switches are used, but a solid ball bearing system. No uncertainty as to which location was chosen. Unused positions are automatically grounded to reduce noise interactions and possible sparking. The popular Alpha Delta Arc-Plug™ Cartidge protects the in-use position. The antenna in the in or out position is always protected in both cases! The Arc Plug is easily accessible from the front panel so you can mount the switch on any surface. Both models support full legal power.

The VSWR is less than 1.2:1 up to 150 MHz, and less than 1.5:1 at 500 MHz for the DELTA series with UHF connectors.

Models with N-type connectors have a VSWR less than 1.2:1 up to 500 MHz and less than 1.5:1 at 1.2 GHz.

SO-239 (UHF) switches are rated for 1500 watts CW/FM up to 30 MHz and 1000 watts from 30 to 450 MHz, assuming a VSWR less than 2:1. Higher VSWR values at full power may distort the ARC-PLUGcartridge. 60 dB isolation up to 450 MHz, typically 70 dB below 30 MHz.

Switches with Type N connectors are rated for power up to 1500 watts CW/FM up to 150 MHz, 1000 watts from 150 to 500 MHz, and 800 watts from 500 to 1.2 GHz. NOTE: 1.2 GHz, not 1.3 GHz. 60 dB up to 500 MHz and 50 dB from 500 MHz up to 1.2 GHz. Assuming a VSWR no greater than 2:1.

All models are so low-loss that the interconnect cables usually have more losses than the switches themselves.
