ZOMWAVE High-Performance Low Pass Filter is designed to provide deep suppression of unwanted signals above the cutoff frequency. It features a wide passband covering DC to 21 GHz with low insertion loss, making it an ideal solution for passing desired low-frequency signals while blocking high-frequency noise and spurious signals, ensuring signal integrity across the target spectrum. The filter is built with a precision aluminum alloy shielded enclosure, delivering excellent stopband rejection of ≥50 dB, low passband loss of ≤1.0 dB, and a power handling capacity of up to 15W CW. Its robust construction and standard SMA-Female connectors ensure reliable operation in demanding applications such as communications infrastructure, radar systems, and advanced test setups. This low pass filter is available in frequencies of 18, 19, 20, and 21 GHz. In addition to frequency, phase matching or time delay matching can also be customized according to customer requirements.
