Passive Switch for MRI Applications: MADP-011048
Features dual pair of anti-parallel non-magnetic PIN diodes
Richardson RFPD Inc. announced the availability and full design support capabilities for a passive switch from MACOM Technology Solutions Inc.
The MADP-011048 uses silicon PIN diodes in a non-magnetic surface mount package. There are two sets of diode pairs, constructed in an electrically-isolated, anti-parallel configuration, that operate from 5 to 400 MHz.
The MADP-011048 is well suited for MRI passive switching applications. The PIN diodes become a high Q R-C network under small signal and behave as an effective passive rectifier or short circuit under high RF signal to tune and de-tune the resonant MRI tank circuit. The anti-parallel doublet configuration provides efficient power handling.
According to MACOM, additional key features of the MADP-011048 include:
- Anti-parallel, self-bias configuration
- CT = 3.0 pF, RP = 10 kΩ, VB = 80 V
- > 50 W CW incident power handling @ 400 MHz
- Lead-free 4 mm 8-lead HQFN package
