Mini-Circuits CLM-83-2W+ ultra-wide frequency power limiter

Click2Contact

Mini-Circuits’ CLM-83-2W+ is an RoHS-compliant limiter which protects against ESD and input RF power surges, up to 1.6 W, across a wide frequency range. The rugged limiters, only 0.12 x 0.12 x 0.045″, provide protection for low-noise amplifiers and other sensitive equipment, especially in hostile environments where unwanted signals prevail, such as manufacturing sites, train tunnels and ECM and ECCM. The ultra-wideband, from 30 to 8200 MHz, protects against many different types of unwanted signals.

The product has limiting abilities from +12 to +32 dBm to help prevent burnout of amplifiers and other highly sensitive components; a response time of 2 ns to react instantaneously to limit unwanted high-level signals; a recovery time of 8 ns as a minimal downtime, after unwanted signals are removed, with quick restoration of standard operating levels and a low insertion loss; 0.5 dB typical; and a low VSWR, 1.2:1 typical, which provides minimal degradation of system performance, especially in low-noise amplifiers where input loss is critical.

The internal diodes are bonded to a multilayer integrated LTCC substrate and then hermetically sealed under a controlled nitrogen atmosphere with gold-plated covers and eutectic AuSn solder. The terminal finish on the low-profile case is Ni-Pd-Au. Ceramic, hermetic, nitrogen-filled construction protects against moisture for long-term reliability.
