16-30GHz Cavity Filter High Quality Factory Whosaler
Millimeter Wave spectrum does needs components that maintain performance at both ends of frequency operation. The 16000-30000MHz Cavity Filter from Keenlion can be provided and manufactured as a full 16-30GHz range product with insertion loss of ≤1.5 dB and VSWR of ≤1.8:1. Because Keenlion operates as a B2B factory, every Cavity Filter is built upon receiving an order from the customer, hence we will not stock any of our Cavity Filters for sale from a catalog.

Built To The Specifications Required For Millimeter Wave Products
Millimeter Wave Design Has Narrow Tolerance Limits. In Millimeter Wave Design, a Cavity Filter must exhibit both low insertion loss and good impedance matching throughout a very wide frequency range. The Cavity Filter described herein does exactly that; insertion loss is typically less than 1.5dB over the entire bandwidth from 16 GHz to 30 GHz, and the VSWR is typically less than 1.8:1. This results in a predictable signal behavior, not at the band edges, for which many alternative filters exhibit signal voltage standing wave ratio fluctuations.
Rejection That Protects Your Chain
Stray signals originating from lower and higher bands at 16–30 GHz can slowly degrade your signal quality. This cavity filter has ≥15dB rejection from DC up to 15500MHz andfrom 30500MHz up to 38000MHz, thereby excluding unwanted energy from being introduced into your receiver stages. Edge selectivithy IS what makes this cavity filter a solid front-end for your mmWave bench and/or comm links.
Mechanical Choices That Matter at mmWave
At these frequencies, the housing is part of the electrical design. This Cavity Filter uses aluminum construction with silver surface treatment for stable grounding and corrosion resistance. The 2.92mm-Female connectors are standard for millimeter-wave work, and dimensions are held to ±0.5mm. Since Keenlion is a manufacturing factory, we can adjust frequency range, connector type, rejection depth, or housing size. Tell us what your system needs, and we will build the Cavity Filter to match.
