Analog Devices has released two 44 GHz single-pole, double-throw (SPDT) switches, the ADRF5024 and ADRF5025 in advanced Silicon-on-Insulator (SOI) technology. The two new switches are broadband, with the ADRF5024 yielding flat frequency response from 100 MHz to 44 GHz, while the ADRF5025 from 9 kHz to 44 GHz, with repeatable characteristics better than 1.7 dB insertion loss and 35 dB channel to channel isolation. Both parts support 27 dBm power handling for both through and hot-switching conditions.
The ADRF5024 and ADRF5025 are ideal replacements for PIN diode-based counterparts, as no external components are necessary for bias generation or matching, and signal pins are internally biased at ground (GND) reference to eliminate the need for direct-current (DC) blocking capacitors.
