This new line of HF-ERF™ High-Performance Miniature Bandpass Filters cover the entire HF tactical radio band of 1.5 to 30 MHz while fitting in a low-profile package measuring 2.0” x 2.78”x 0.60” (50.8 mm x 70.61 mm x 15.24 mm). The HF-ERF™ combines SMT capability with typical 0.25 dB compression points at +18 dBm (Fo < 4 MHz), +26 dBm (4.0 MHz < Fo > 10 MHz) and +27 (10MHz < Fo > 30 MHz) in-band and +33 dBm out-of-band RF power handling, +28 to +38 dBm IIP3, low IL (5.5 dB typical in a 3% filter), 200 μs typical tune time and remarkable selectivity (33 dB Typical @ f₀ ± 10% for 3% BW) for a compact device. HF-ERF™ filters tune using either Parallel or Serial Peripheral Interface (SPI) tuning control and are fully pre-aligned by Pole/Zero for labor savings and ease of use. These low-cost bandpass filters are commonly used in applications where small size, low power, and high performance are needed such as military handheld radios, radar systems, SATCOM, test and measurement systems and additional commercial applications.

The MINI-POLE® is optimized for size, RF power handling, low distortion, and exceptional selectivity. The MINI-POLE® comes in a compact 42  in DIP package 0.558 x 1.305 x 2.250 inches (14.17 x 33.15 x 57.15 mm.)

The MINI-POLE® uses a high factor pin diode switched capacitor array with a customized high voltage driver to accurately and reliably tune to pre-defined frequencies. The MINI-POLE® is primarily used in applications where adjacent radio channels may cause interference on the acquisition channel. The MINI-POLE® can be  used to reduce or eliminate the effects of these interfering signals but it is flexible enough to be used in a multitude of applications.

The MINI-POLE® uses an 8-bit wide proprietary parallel or serial interface to tune to a maximum of 251 tune positions per band. The MINI-POLE® will typically tune in less than 10 μs. The MINI-POLE® requires only two external power supplies, +5V and +100V.

All MINI-POLE® filters are fully aligned and tested by POLE/ZERO® for convenience and ease of use. The MINI-POLE® covers six frequency ranges and custom configurations and designs are available upon request.
