Microsemi
Founded in 1960, Microsemi Corporation is a leader in the manufacture of RF and Microwave semiconductors and subsystems for the medical, broadband communications, defense and aerospace markets. Major products offered include discrete semiconductors and RF components.
Microsemi’s Microwave Products
The Microwave Products operation, located in Lowell Mass., brings nearly 30 years experience in manufacturing high reliability RF and Microwave PIN and limiter diodes, tuning and multiplier varactors, noise diodes, Schottky-barrier diodes, MNS chip capacitors and solid state control modules. Frequencies range from 100 Hz through millimeter wave.
With high volume wafer fabrication now in place to meet the competitive needs of our growing commercial customer base, Microsemi’s Lowell facility can deliver more cost-effective components faster than ever for our long standing military customers as well. From our closely controlled RF/Microwave diode inventory we can match characteristics precisely to maintain consistent component performance levels over the full life of your system designs.
Our Lowell operation builds RF and Microwave PIN diode switches, limiters, comb generators, and detectors in frequency ranges from 2 MHz to 20 GHz. All can be hermetically sealed to meet the most stringent military or space requirements. To assure the engineering expertise that will attain your desired performance levels,
Microsemi only provides assemblies where we can control the high risk components. In that way, we’re able to develop custom packaging that meets your most demanding specifications. Microsemi also can offer a significant number of existing configurations to minimize your NRE and provides many customers with microwave components no longer available from their original suppliers.
Devices include:
PIN Diodes
Limiter PINS
Planar Beam Leads
Mesa Beam Lead PINS
Ceramic MELF PINS
Monolithic Microwave Surface Mount (MMSM) Micro-Pak PINS
Power PINS
Schottky Mixer Diodes

Microsemi Power Products Group
The Power Products Group was created in 2006 with the acquisition of Advanced Power Technology, Inc., a company at the forefront of power semiconductor technology since its founding in 1984. Significant within this Power Products Group is the RF Power Products operation, originally known as GHz Technology Inc. prior to its acquisition by APT. This new Microsemi organization offers products featuring Bipolar, VDMOS, and LDMOS technologies. All of its products are based on silicon and span the frequency range from 1MHz to 3.5GHz using supplies from as low as a few volts to as high as 300 volts.
RF Power Products facilities are located in Santa Clara, California and Bend, Oregon. In addition to our internal wafer fab and assembly, products are assembled in facilities operated by our production partner in Malaysia. We offer products that are ISO9001 registered, space qualified, and Mil Standard approved. Our automated assembly and final RF Test lines are among the most modern in the world, assuring consistent quality and reputable performance.
We support our product roadmaps with continuing investment in new technology and product developments structured to set performance standards in applications for Broadcast, ISM, Avionics, L-Band Radar, and pulsed LDMOS.
Product Features
- Bipolar, LDMOS and VDMOS Transistors designed for specific CW or Pulsed applications
- Gold Metallization for longest lifetime
- Automated Assembly for tightest production control and lot-to-lot consistency
- Internal pre-match for best performance over the entire operating frequency range
- Automated RF testing over the operating band to ensure specified performance
- Custom parts optimized for their applications and tested in correlated fixtures to agreed-upon specifications
- Hi Rel screening performed to selected levels: JAN, JAN-TX, JAN-TXV, JAN-S
Our Mission Goals
Our mission is to be the world leader in high power silicon RF & Microwave power transistors for applications in Avionics, Broadcast, Communications, ISM, and Radar. We will continue to push the performance envelope with the new product we introduce.
Our goal is to provide the customer with products that meet all specified requirements, with performance that is consistent from lot-to-lot while meeting the reliability requirements over the life of the program. This ensures that our customers achieve the optimum system performance and the lowest total cost of ownership.
