HLM-8010CSP1_DC - 40GHz Surface Mount Limiter

Device Overview

General Description

The HLM-8010CSP1 is a high-power GaAs Schottky diode signal limiter featuring high IP3 over a broad DC - 40GHz bandwidth. It offers low insertion loss and excellent return loss from DC through Ka band and has a typical 1 dB compression point of +11 dBm. Its small size makes it ideal for protecting sensitive components and for applications requiring high channel counts. It is available as a plastic surface mount chip scale package or as a connectorized evaluation board.

Input Power at Observed Failure

Power handling specification is based on tests performed at different combinations of temperature and frequency. Input power was increased until catastrophic failure was observed. Results are shown in the following table. The power handling specification listed in section 3.1 is based on the worst observed power handling derated by 2dB.
