RF/Microwave Diodes, Passive Semiconductor Devices
Established in 1986, MicroMetrics, Inc. is a full service manufacturer of standard and custom RF/Microwave Diodes and Semiconductor Devices for commercial and military communications. It designs and develops drop-in solutions for customers demanding applications. Whether your needs are for a high performance diode, a discontinued device from another manufacturer, or a uniquely designed solution, MicroMetrics prides itself in its ability to respond. From sales support to application assistance MicroMetrics is commited to its customers.
In February of 2007, MicroMetrics has announced the release of new non-magnetic metal electrode leadless faced (MELF) packaged PIN Diodes that feature high power handling and low distortion. These MELF PIN Diodes are designed for switching and attenuator applications from HF through UHF frequencies. They're manufactured using MicroMetrics' propriety glassing process which features full-face bonding on the anode and cathode of the device to ensure full surface contact of the square ceramic package. This creates lower electrical and thermal resistance and provides higher average performance at RF power levels up to 100 Watts CW. They also feature low series resistance which leads to low inductance characteristics, and low junction capacitance, which delivers high isolation. As a result, this family of PIN devices has lifetime specifications that will allow for lower intermod distortion and have a higher average incident power handling capability. The electrical and mechanical specifications of these devices meet the requirements of MRI systems.
These hermetically sealed devices have been designed for high volume tape and reel assembly utilizing the ceramic package flat surface for automatic pick and place assembly or vacuum pickup techniques.
All solder surfaces are tin plated and compatible with reflow soldering methods. Package types available include the new surface mount ceramic package CS127-1 and standard MELF CS127-4. These devices can also be delivered in chip form or in custom specified packages.
