GaAs pHEMT Switches for GSM HandsetsCOVER FEATURE2.5 V GAAS PHEMT SWITCHES FOR GSM HANDSETSAnew line of robust GaAs pHEMT switches for operation in 2.5 V GSM handsets has been developed. These switches feature performance that is unrivaled in the industry for harmonics at 2.5 V in addition to offering low insertion loss, high isolation, low current, small size and low cost. The key to these performance levels has been to leverage the company’s advantages in circuit design, modeling, pHEMT processing and miniaturized packaging into cost-effective products that are shipping in high volume to meet the demands of current and next generation cellular phones. These products have superior harmonic rejection versus control voltage characteristics. Unlike other competing products which nominally work closer to 3 V, these switch……
