M/A-COM, a business unit of Tyco Electronics and a provider of wireless RF, microwave and millimeter wave components, released a family of nonmagnetic, high-power PIN diodes suitable for use in Magnetic Resonance Imaging (MRI) circuits and test equipment.

Manufactured using a proprietary and patent pending plating process, members of the MA4P7400 series are available in the Metal Electrode Leadless Faced (MELF), 1072 and 1091 ceramic surface-mount packages. According to the company, these packages are 100 percent tested for hermeticity and are similar in electrical performance to their magnetic MELF counterparts.

The silicon PIN diodes employ full faced anode and cathode contacts to lower the effective electrical and thermal resistance. This lower series resistance of the PIN diodes also improves harmonic distortion and intermodulation products in the lower HF frequency bands, M/A-COM added.
