High-Pass Filter（RSL-H2400CA）

Product Introduction:

The RSL-H2400CA 2.4–8.4 GHz RF high-pass filter is designed for broadband RF and microwave systems that require reliable low-frequency rejection with low signal loss across a wide operating band. It provides a 2400–8400 MHz passband, insertion loss of ≤1.2 dB, passband ripple below 1.0 dB, and VSWR <1.5. The filter delivers strong out-of-band suppression of ≥35 dB from DC to 2100 MHz and ≥25 dB at 2140 MHz, helping reduce unwanted low-frequency interference while maintaining stable signal transmission. A standard 50-ohm impedance, dual SMA female (SMA-K) connectors, compact 30 × 12 × 10 mm housing, and -40°C to +70°C operating temperature range make it well suited for integration into space-constrained RF equipment and demanding system environments.

With its 2.4–8.4 GHz wideband frequency coverage, compact form factor, and high stopband attenuation, the RSL-H2400CA is suitable for a variety of RF filtering and microwave signal-conditioning applications, including wireless communication systems, RF test and measurement equipment, broadband transceiver front ends, laboratory RF systems, communication infrastructure, and other applications requiring suppression of signals below 2.4 GHz. Its wide passband and SMA interface also make it a practical choice for RF system integration, interference suppression, signal chain optimization, and custom microwave assemblies where low insertion loss and broadband operation are important design requirements.
