50 to 75 ohm Impedance Converters

A range of high performance 50 to 75 ohm Impedance Converters designed for satellite IF signals. These are based on a microstrip transformer for lowest loss. The cases are machined from Aluminium alloy and have a Nickel plated finish.

Typical loss < 0.2dB

Passes DC, 10MHz and FSK.

Options include blocking of  DC and/or 10MHz

New  Type28 available  for 50 to 180MHz

1U panel for up to 12 units mounts horizontally to front or rear rack uprights.

Rack side mount bracket for units, single to 16 way to mount vertically on one side in rear of rack.

50/75 ohm

A "lossless" impedance transformer having several advantages over the more common Minimum loss pads. It is a high quality microstrip transformer with loss of less than 0.2dB and a return loss of 20dB at both the 50 ohm and the 75ohm ports. It is able to pass DC and 10MHz reference signals when they are required for BUCs or LNBs.Alternatively DC blocking can be specified.
