IN MY OPINION
The 2016 Defense Budget in Perspective
By Barry Manz President Manz Communications, Inc.
Determining the “right” level of funding needed to keep America safe is at least as difficult today as it has ever been, which explains why in addition to the Congressional Budget Office and other government agencies, think tanks, historians, academics, former government officials, and countless others dedicate their careers to the endeavor.

xxx Low Powered VCO
The V480MEM2-LF RoHS compliant VCO operates at 445 to 480 MHz with a tuning voltage range of 0.5 to 2.5 Vdc. It features a spectrally clean signal of -113 dBc/Hz @ 100 kHz offset and a typical tuning sensitivity of 25 MHz/V. It typically draws just 12mA of current.
Z-Communications
xxx Ultra Low Noise MMIC Amplifier
The CMD163 is a 17 to 27 GHz low noise amplifier (LNA) in die form. It has a gain of +24 dB, a noise figure of less than 1.3 dB, and an output 1 dB compression point of +19 dBm across the bandwidth. The CMD163 utilizes an all-positive bias scheme, eliminating the need for negative voltages and expensive sequencing circuitry. Bias conditions are Vdd–4V @ 120, MA and Vgg = 3.0 V.
Custom MMIC
xxx Conduction Cooled Termination
Model series 552-308-050 is a 50W of RF power (average) rated conduction cooled termination that has been deployed in military applications. This 50 ohm device has an operating frequency range of DC to 4 GHz and features maximum VSWR of 1.35:1. The RF connector is N male. Additional heat sinking is required for safe operation of this device at 50W (case temperature must be maintained at +100ºC or less). The nickel plated copper enclosure provides excellent thermal conductivity at an affordable price. Conduction cooled terminations are appropriate where space is limited and heat dissipating metal is available.

Uncertain Times for DefenseWill OpenRFM Shake Up the Microwave Industry?
By Barry Manz

Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...
