| High Frequency Surface Mount Attenuators PCH1632 Series * RoHS compliant * Operation frequency up to 1.5GHz * Ideal impedance conversion solution * Low cost surface mount construction The PCH1632 series impedance converter provides impedance conversion between the two most common characteristic impedances in use, 50 and 75. The PCH1632 series provides impedance conversion across a frequency bandwidth of DC to 1.5 GHz with an insertion loss of 6dB. Typical applications include telecommunication and networking equipment as well as applications. Thin film construction provides consistent operational stability over temperature and time.
