The Model 4044 from Bird Technologies is an economical, non-directional power sensor that operates from 144 MHz to 960 MHz. It measures the output power of either analog or digitally modulated radios with a power range up to 100 W. This sensor is a non-directional sensor that is ideal for use at the input to each channel of the transmit combiner where the VSWR is well controlled. It has a VSWR of less than 1.07:1, an insertion loss of less than 0.1 dB and PIM of less than -145 dBc. It is matched to 50 Ohms and is available with N type male to female connectors. It requires a supply of 7/18 Vdc at less than 50 mA of current.
