IQD Frequency Products has introduced the new IQXF-1000 series, a range of band-pass filters with center frequencies from 1.4MHz to 200MHz based around fundamental and third overtone mode crystals.
The new two to 12 pole crystal filters can operate over a temperature range of –55 to +85 degrees C with a bandwidth @3dB from ±2kHz and with the passband ripple as low as 0.5dB and insertion loss down to 2.5dB, the company said.
The filters are ideal for commercial and military grade mobile radios (HF, VHF, UHF, S-band), microwave link data communications, radar scanning in navigation and avionics, and medical instruments such as MRI machines.
