Innovation: The Answer to a Flat Market
By Harvey Kaylie, Founder and CEO, Mini-Circuits
Some might say business seems flat lately. The financial crisis in Greece has led to economic turmoil in the EU. Opportunities in China have slowed, and when China sneezes, the whole world feels it. Read More...

SP6T RF Switch
JSW6-33DR+ is a medium power reflective SP6T RF switch, with reflective short on output ports in the off condition. Made using Silicon-on-Insulator process, it has very high IP3, a built-in CMOS driver and negative voltage generator.

Group Delay Equalized Bandpass Filter
Part number 2903 is a group delayed equalized elliptic type bandpass filter that has a typical 1 dB bandwidth of 94 MHz and a typical 60 dB bandwidth of 171 MHz. Insertion loss is <2 dB and group delay variation from 110 to 170 MHz is <3nsec.
KR Electronics

Absorptive Low Pass Filter
Model AF9350 is a UHF, low pass filter that covers the 10 to 500 MHz band and has an average power rating of 400W CW. It incurs a rejection of 45 dB minimum at the 750 to 3000 MHz band, and power rating of 25W CW from 501 to 5000 MHz.

LTE Band 14 Ceramic Duplexer
This high performance LTE ceramic duplexer was designed and built for use in public safety communication and commercial cellular applications. It operates in Band 14 and offers low insertion loss and high isolation to enable clear communications in the LTE network.

xxx GaN RF Power Amplifier
The AML218P4013 GaN RF power amplifier delivers 20W of saturated output power with 16% power added efficiency from 2 to 18 GHz. It operates from a +32 VDC single bias supply, has an operating temperature range of -40 to +85ºC and is housed in a 3.5 x 1.9 x 0,45” connectorized module.
xxx Directional Coupler
To support development of C-band radar sub-systems, the company has developed a 5 to 6 GHz 40 dB coupler, Model 12A7NA-40S, with very low insertion loss and high directivity. Other coupling values are also available in the same package size.
Renaissance Electronics
xxx Reduced SWaP-C MINI-ERF (G2) Bandpass Filters
Model MN-30-520-(%BW)-S04 is a new reduced SWaP-C line of MINI-ERF (G2) tunable bandpass filters. It covers the entire tactical military tuning range of 30 to 520 MHz and is currently available in either a 4% BW or 7% BW (3 dB). The MINI-ERF (G2) filter is a low-cost, miniature, high-performance tunable bandpass filter that uses PIN diodes to deliver high dynamic range while fitting in a 1.75 x 2.40 x 0.387” package. It combines SMT capability with 1W (input) in band and up to 2W (input) out of band RF power handling, +40 dBm IIP3, low insertion loss, good selectivity and fast tune time (15 µs typical @ 0 dBm). The digital interface format can be either SPI serial or parallel.
xxx Frequency Synthesizers Extended to mmW
The QuickSyn Lite frequency synthesizers are now extended to millimeter wave. The new modules are available in three popular bands – 27 to 40 GHz, 50 to 67 GHz, and 76 to 82 GHz – and are designed to supply medium power output.
National Instruments
xxx Detectors/Limiters
The company’s broad range of RF and microwave detectors and limiters also includes detectors with built-in limiters to protect the diode from potentially damaging signals. Tunnel, zero bias, biased Schottky, pulse present, threshold, and waveguide type detectors are available up to 50 GHz.

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...
