Tunable bandpass filters for military handheld radios and radar systems introduced by Pole/Zero


Pole/Zero Corp. in West Chester, Ohio, is introducing the 2W-ERF tunable bandpass filters covering the military tactical radio band of 90 to 520 MHz for military handheld radios, radar systems, satellite communications (SATCOM), and test and measurement systems.

These RF and microwave devices are for applications where small size, low power, and high performance are needed, measure 2 by 2 by 0.29 inches and combine surface-mount technology (SMT) capability with +33 dBm (2 Watt) in-band and +37 dBm (5 Watt) out-of-band RF power handling, +40 dBm IIP3, low IL.

3.2 dB is typical in a 7 percent BW (3dB) filter, 15 microseconds typical tune time and remarkable selectivity (15 dBc at fc ± 10 percent for 7 percent BW) for a compact device.

These 2W-ERF low-cost bandpass filters can be tuned in either serial or parallel mode and are pre-aligned by Pole/Zero for labor savings and ease of use. For more information contact Pole/Zero online at
