Tunable bandpass filter meets military standards
A new 30–520MHz tunable bandpass filter and associated evaluation board from NewEdge Signal Solutions is available at Richardson RFPD with full design support. The SAX239 offers a 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.
It 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).
An associated evaluation board includes the filter and the interface required to allow control from any PC.
Additional key features of the SAX239 include insertion loss of < 4.5 dB (typ.) over the full 30–520 MHz band, step size at 1.0 MHz (30–88 MHz) / 2.0 MHz (90–520 MHz) and tuning speed of 40 µs (max.) / 25 µs (typ.).
Dimensions are 1.2 x 1.2 x 0.25 inches.
