We are proud suppliers of commercial, MIL, and space-rel devices for such prominent companies as Raytheon, Hughes Missile Systems, E-Systems, MITRE, M/A-Com, BAE Systems, and Alpha.

Products

We are proud to provide some details on some of our main product lines, which include...

• PIN Diode Drivers

Hybrid circuits that accept TTL, ECL, PECL (or whatever logic you use) and provide the currents and voltages to drive your PIN diode switch.

• Linearizer Hybrids

Hybrid circuits that take an analog voltage or current and provide an output voltage or current with a user-adjusted curve, such as for linearly driving PIN or GaAs attenuators, Varactor-controlled circuits, or for linearizing the outputs of sensor devices.

• Obsolete & DMS Replacements

We are your best source for drop-in replacements for National Semiconductor obsolete hybrids, such as the LH1605, LH0010, LH0021, LH0041, and the DH0035.  MIL-screened, improved, and/or commercial versions are available, in various packaging options.

• MEMS Drivers

Impellimax provides a broad line of MEMS drivers, tailored to the specific drive needs of the various MEMS technologies in this rapidly advancing area of technology.

• GaAs MMIC Switch Drivers

Hybrid or SMT devices that convert a logic level command into the negative complementary output voltages that are needed to drive typical GaAs MMIC switches.

• Multifunction and Special Assemblies

What you need is what you get... SMT, MCM-L, COB, thick or thin film hybrid, or any useful combo that we need to do, to make your design happen.

Services

Depending on your own in-house needs and capabilities, you may find our related services to be a useful adjunct...

• Hybridization

Honey, I shrunk the PC board! We can work from your existing circuit diagrams to create a miniaturized version of your proto or production assembly, probably all in one little chip.

• Virtual Tweaking

We have developed software which allows us to take in your data file (such as the Current vs Attenuation of an attenuator) to optimize our designs for your devices.

• "DC Side" Management

RF and Microwave designers deal with an "RF side", which has diodes and transmission lines, and a "DC Side", which has TTL interface specs, bypass caps, reverse protection, and lots of other things that we can take care of for you, so that you can concentrate on the "RF side".

• Driver / Diode Testing

If you can supply us with an RF unit, or with loose RF diodes (in chip or any packaged form), we can build up a realistic dummy load and verify that the driver and diode are going to work for you in your product.
