This study reports the design, development and analysis of centre frequency and bandwidth (BW) reconfigurable multi‐mode band‐pass filter with independently tunable transmission zeroes (TZs). The designed filter can tune lower TZ ( T Z 1 ) from 1.66 to 1.88 GHz (220 MHz) with lower‐side BW tuning range 200–400 MHz and upper TZ ( T Z 2 ) from 2.32 to 2.48 GHz (120 MHz) with upper BW tuning range 430–630 MHz. The centre frequency of the designed filter can be tuned from 1.98 to 2.04 GHz (60 MHz). For the entire tuning range, the insertion loss of the designed filter is around 1.4–2.3 dB and return loss is better than 10 dB within the pass‐band.
