IMS 2016 Demonstrates Innovation

Skyworks' new SKY66184-11 power amplifier.

The 2016 edition of the IEEE International Microwave Symposium (IMS) is now behind us. The event had something for everyone who attended—far more than I am discussing here. For myself personally, I enjoyed seeing the live demonstrations that many companies offered. Although I was not able to see them all, some of the demonstrations I did see were pretty impressive. Below are some of the ones I was able to catch.

At IMS, Skyworks announced a new line of power amplifiers (PAs) for small-cell applications that consists of the SKY66184-11, SKY66185-11, and SKY66186-11 models. The company demonstrated the performance of the SKY66184-11 PA at +85°C, proving at that temperature that the PA can deliver +23 dBm of output power with an adjacent-channel leakage ratio (ACLR) of -50 dBc. The SKY66184-11 covers a frequency range of 2,110 to 2,170 MHz.

Broadcom Limited demonstrated its new LTE carrier aggregation (CA) hexaplexer. This hexaplexer, which the company says is the industry’s first, is scheduled to be released early next year. It utilizes film-bulk-acoustic-resonator (FBAR) filters to offer breakthrough performance in a very small size. Broadcom also demonstrated its 60-GHz wireless mesh chipset solution, which is intended for wireless infrastructure applications.

A 1200-W gallium-nitride (GaN) 2-stage PA was demonstrated by Microsemi. The setup was built to utilize one of two possible devices for the driver stage: The 1011GN-15EL or the DC35GN-15-Q4. The output stage was designed with the 1011GN-1200V high-power device, which can provide a power gain of 20 dB and can achieve a typical drain efficiency of 75%.

A number of products were demonstrated by MACOM, including the company’s new MAMF-011057 E-band transmitter (Tx) module. This module, which has a WR-12 waveguide output interface, can cover a frequency range of 71 to 86 GHz. And though it wasn’t demonstrated at IMS, MACOM also announced the new MADC-011014 E-band receiver (Rx) module.

In addition, Wireless Telecom Group conducted several demos to allow visitors to learn more about the company’s test capabilities. One of these demos incorporated a UFX7000A Series broadband noise generator and the USB 55006 power sensor to test a communication or radar system’s immunity to noise, jamming, or interference. A pulsed test signal with simulated orthogonal-frequency-division-multiplexing (OFDM) modulation served as the input to the UFX7000A, while the broadband noise level was varied. The output of the UFX7000A was connected to the USB 55006 power sensor to display carrier-to-noise ratio (CNR) measurements.
