Product Details

For impedance transformation/isolation applications when max power is 5 Watts PEP, this transformer provides a simple interface between transmission lines with different connectors or impedances or simply common mode isolation. DC continuity for bias-T applications.

Features

- Cast Aluminum die-cast enclosure for excellent shielding and ground continuity between receiver and coaxial shield

- Wide frequency range of 3-30 MHz with SWR under 2:1 across the entire range

- Typical input impedance from 45-55 ohms, Output impedance 50-800 ohms depending on ratio selected

- Small compact size - length (tip to tip of N connectors) = 3.625", Width = 1.5", Height = 1.2"

- Low insertion loss

Power rating: 1.5 Watts (31.8dBm) 100% duty cycle, 3.0 watts (34.8 dBm) 50% duty cycle (CW), 5 watts (37 dBm) 30% duty cycle (SSB/PEP)

Impedance ratios available from 1:1, 2;1, 4;1, 6:1, 9:1, 12;1, 16:1

Connectors: SO-239, N, BNC, SMA

Picture shows 50 ohm input, 800 ohm output with N connectors

Receiver Only Unun transformers are made to order with manufacturing time of 5 or more days before shipment depending upon quantity.

Mobile RFI kits work two ways: They suppress RFI from on board computers and other sensing/control devices in your vehicle that may cause your radio to be a VICTIM of RFI, and second they suppress RFI generated by your radio as a SOURCE which may affect your on board computers or other devices.  Mobile operations of HF radios (1-30 Mhz) tend to experience more RFI effects than VHF/UHF mobile stations.  If you have both HF and VHF installations in your vehicles, you may need both kits.

To address separate solutions we have developed two separate RFI kits: one for HF (1.8-300 MHz) mobile installations and another for VHF/UHF (30-1000 MHz) mobile installations.  Each kit uses the appropriate ferrite mix for the frequency range desired.
