Microsemi Corp., announced the availability of a series of new plastic packaged PIN diode control products. The new devices are highly cost competitive and can provide higher RF functionality, helping defense, aerospace and medical customers reduce bill of materials (BOM) costs with low risk and little sacrifice to performance.

Our test and measurement, communication radio, radar and MRI customers all require an increased level of functional integration coupled with form factor reduction, which is consequently driving the need for PIN diode switches with higher density, functionality and performance,” said Kevin Harrington, director of strategic marketing for Microsemi’s RF/Microwave Discrete Products business unit. “Our new PIN diode switches are both integrated and compact in surface mount plastic packaged formats which further enables superior RF performance.

The new product families, all RoHS-compliant, include:

MPS4101-6LP, a single pole single throw (SPST) PIN switch with a 3mm QFN-packaged series/shunt element offering wide-band, low-loss and high-isolation performance;
MMP4400, a series of five high-voltage, high-power PIN diode devices in plastic surface mount technology (SMT) packages with high stability and reliability, as well as low thermal resistance, high shunt isolation and low distortion;
GC4701-6LP, control devices with a SMT PIN limiter element, providing a specially processed PIN diode packaged in a convenient, low-cost plastic outline suitable for standard or co-planar microstrip circuits that comes in a 1.6mm QFN package and offer low insertion loss, low threshold power and high isolation; and
MML4400, a series of fast surface mount MRI protection diodes offering protection from high-RF energy fields and enabling passive switching of surface-coil detuning and blocking circuits. The devices offer an anti-parallel option (unconnected pairs) in addition to low capacitance and conductance.
Challenging other PIN diode product suppliers in the market, Microsemi’s new devices are designed to support the company’s cross-selling opportunities alongside existing products into a variety of aerospace, defense and industrial applications such as test and measurement, MRI equipment, electronic warfare and radar.

Specific examples for each new device include:

MPS4101-6LP SPST PIN switch: receiver/transmitter and filter switching, receiver protection, attenuators in electronic warfare (EW) systems, channel switching in high linearity microwave radios, filter switching and receiver protection in military and land mobile radios
MMP4400 series: receiver/transmitter and filter switching, receiver protection, attenuators in EW systems, channel switching in high linearity microwave radios, receiver protection in military and commercial radar, channel switching in very small aperture terminal (VSAT) and satellite communication (SATCOM) applications, filter switching and receiver protection in military and land mobile radios
GC4701-LP diode limiter: RF bench-top and RF portable instrumentation, receiver/transmitter and filter switching, receiver protection, attenuators in EW systems, channel switching in high linearity microwave radios, receiver protection in military and commercial radar, channel switching in VSAT/SATCOM applications, filter switching and receiver protection in military and land mobile radios
MML4400 series fast surface mount MRI protection diodes: high-speed detune elements for patient protection in MRI equipment
Microsemi’s newly launched PIN diode families are ideal for these growing markets, as they combine lower cost surface mount packaging, fast switching and high continuous wave (CW) power handling capability, without sacrificing overall RF performance specifications.

Microsemi’s series of new plastic packaged PIN diode control products are available now.
