Lark offers a full line of ultra-thin filters for commercial and military markets. Lark’s new ultra-thin package offers superior performance in less than 0.09” high package with low insertion loss and ultimate rejection levels of 60 dB while maintaining better than 1.5:1 VSWR. Units are lightweight and ruggedized for today’s AIR, SEA & LAND applications.

DiTom Microwave has released a new Ka-Band Isolator 27 to 31 GHz. This Isolator covers both the military and commercial Ka-Band applications and is available with 2.92mm female or male connector configurations. DiTom Microwave can improve these electrical specs for high reliability use and narrow the band if necessary.

S2D Microwave Inc. offers broad band 0.5 to 20 GHz, high performance 3 Bit, 60 dB switched bit attenuator. S3-AS6055R520 is a high performance compact unit with low insertion loss, fast switching speed, low harmonic distortion, Three-bit attenuation control has TTL driver.

RFMW Ltd. announces design and sales support for Johanson Technology’s (JTI) newly introduced 2.4 GHz, high-rejection bandpass filter (BPF) with land grid array (LGA)-type terminations. This brand new BPF has the highest close-to-passband rejection with the smallest footprint ever made by JTI.

Integrated Microwave Corp. offers a high-frequency true elliptic function highpass filter. This small-profile filter offers a nominal passband insertion loss of 0.7 dBa at 5.2 to 13 GHz. This superior rejection provides 20 dB at 4.9 GHz, and -40 dB nominal DC to 4.8 GHz, with a 3 dB cutoff at 5.15 GHz.  Performance is comparable to a suspended substrate, but at one-quarter the size and cost.

The DL82030 is a broadband 8-way power divider that is suitable for radar and SatCom applications from 20 to 3000 MHz. This reliable 8-way ferrite component is designed for systems requiring an even division of input power, providing signals at 8 output ports that are well balanced in amplitude and phase.

Vaunix Technology, a manufacturer of USB controlled and powered test equipment, has three models in their family of LDA series digital attenuators. This product family offers attenuators with up to 90 dB of programmable attenuation through 6 GHz.

The UK’s Nanotechnology Knowledge Transfer Network (NanoKTN) announced details of a product developed by Plessey Semiconductors, as part of a project co-funded by the Technology Strategy Board (TSB), with support from the NanoKTN and JEMI UK.

Doherty combiner product line covers major communication bands ranging from 700 MHz to 2700 MHz. Each model is optimized for the center frequency of targeted frequency band. However, as new spectrum is being released, the pre‐designed standard models can be tuned in customer applications to meet performance. This document provides guidelines to tune these standard models for off‐band applications.

With today's advancements in wireless technology, greater emphasis is being placed on component performance. This article will provide a discussion of ceramic and porcelain chip capacitors and understanding their behavior in RF product designs. They are an excellent choice for wireless applications where volumetric efficiency, reliability and RF performance are an absolute must.
