Richardson RFPD Introduces Tunable Bandpass Filter from NewEdge Signal Solutions
Richardson RFPD announced the availability and full design support for a new tunable bandpass filter, covering 174 to 512 MHz, from NewEdge Signal Solutions.
The SAX270 electronically-tunable bandpass filter was designed for the extended UHF band in tactical communications applications. NewEdge used what the company describes as “a breakthrough approach” to achieve the filter’s extremely small size with over-molded plastic packaging.
The combination of size and RF performance with low DC power consumption makes this filter well suited for high performance embedded applications where board size is constrained, such as handheld and manpack radios or embedded radios in drones and other airborne platforms.
Key Features of the SAX270
