Radio transmit modules continue to shrink in die size and cost, requiring novel approaches for integration of the numerous passive elements of the radio front-end.  An established based on low cost mechanical grade Lec GaAs substrates, for application including impedance matching, filtering and switching.  Low pass harmonic filters integrated with coupler for AMPS/GSM 824-915 MHz and PCS/DCS 1710-1910 MHz bands were designed and fabricated showing excellent performance.
