SP4T Switch
Analog Devices has two MEMS switches, these are the ADGM1304 and ADGM1004. They are both SP4T multiplexers with DC (0 Hz), precision performance to 14 GHz and 13 GHz bandwidths respectively. The key difference between these parts is the higher ESD rating for ADGM1004. The RF pins of the ADGM1004 part have a very high HBM ESD rating of 5 kV, with all other pins rated up to 2.5 kV. Key performance details of the ADGM1304 and ADGM1004 includes Ron of 1.6 Ω and 1.8 Ω respectively, Power handling of 36 dBm and 32 dBm respectively and IIP3 performance of 69 dBm and 67 dBm respectively. Both devices run off VDD of 3.3 V. ADGM1304 Insertion Loss and Off Isolation is also shown on this slide, with typical IL performance of 0.26 dB at 2.5 GHz and 0.4 dB at 6 GHz. Off Isolation is typically 24 dB at 2.5 GHz and 19 dB at 6 GHz. Both the ADGM1304 and ADGM1004 parts are guaranteed, for cold switching lifetime, up to 1 Billion cycles up to a max operating temperature of 85oC. 220 mA of current can be passed through the switch when turned on.
