Geneva, IL. Richardson RFPD has announced the availability of and full design support capabilities for a new 30- to 520-MHz tunable bandpass filter and associated evaluation board from NewEdge Signal Solutions Inc.

The distributor says the SAX239 offers an industry-leading combination of power handling (+33 dBm) and DC power consumption (< 100 mW) in a small form factor. The new device also features low insertion loss and fast-tuning across the band to 1.0-MHz resolution.

The new device is designed for tactical communications applications and offers full environmental qualification, including vehicular (to MIL-STD-810G, Method 514.6) and jet fighter (to MIL-STD-810F, Method 514.5G) applications.

An associated evaluation board includes the filter and the interface required to allow control from any PC.

The SAX239 offers these additional key features:

• insertion loss: < 4.5 dB (typical) over the full 30- to 520-MHz band;
• step size: 1.0 MHz (30 to 88 MHz) / 2.0 MHz (90 to 520 MHz);
• tuning control: serial (SPI);
• tuning speed: 40 µs (maximum) / 25 µs (typical);
• IIP3: +45 dBm;
• bandpass bandwidth: 3.5% typical;
• bandpass VSWR: 1.5:1 typical: 2.0:1 maximum; and
• dimensions: 1.2 x 1.2 x 0.25 inches.
