We present a package for capacitive RF-MEMS switches that is based on laminate substrates and BCB-sealed glass caps. The assembly is realised using standard packaging equipment. The package is only 1.1 mm thick, gross leak tight, has high mechanical strength, and passes accelerated lifetime testing. RF insertion loss was lower than 0.6 dB below 15 GHz. Capacitive switches packaged by the proposed method reach a lifetime of 10/sup 7/ cycles, and sustain 1000 h exposure at 85/spl deg/C/85%RH.
