Different functions of the switches include or omit a shunt

inductor from the circuit. Changing the shunt inductor value

affects the bandwidth and center frequency of the filter. Using

inductance values from 15 nH to 30 nH significantly alters the

bandwidth and center frequency, allowing the filter to dynamically

configure to operate in the UHF band or very high frequency

(VHF) band while preserving the 50 Ω match on the input and

output ports. The low RON value and large bandwidth of the MEMS

switch makes it an ideal choice for dynamic configuration. The

low RON reduces the negative effect a series resistance has on the

quality of the shunt inductor. The large bandwidth enables

higher frequency band-pass filters.
