Abstract
This paper presents the results of an antenna switch module integrating a switch (SP9T) and two low-pass filters for harmonic rejection on a low temperature co-fired ceramic (LTCC) substrate. This contributes not only to reduce the size and weight, but also to shorten the development term of RF circuit and simplify the assembly process. It will be used for GSM/UMTS dual mode cellular phones. The 50-ohm in/out FEM utilized a GaAs PHEMT switch is attached to the LTCC substrate. S-parameter characterization of FEM demonstrated excellent insertion, return loss and isolation characteristics of ASM. The final three-dimension model occupied a volume of 4.5 mm × 3.2 mm × 1.4 mm.Keywords
