Amplifiers and Oscillators Download the Puzzler (PDF) Across 2 A polynomial model for nonlinear behavior that accounts for memory effects (2 words) 5 Short for digital pre-distortion 9 mm-wave frequency best suited for high bandwidth, short-range applications due to high atmospheric attenuation 10 Random fluctuations in the phase of...

The emergence of Long Term Evolution (LTE) as the next generation mobile wireless standard beyond 3G renews the importance of broadband, highly linear RF systems and components. The deployment of LTE in the 700 MHz spectrum in the United States only increases an already crowded spectrum, raising the bar...

Over the past 20 years, RF and microwave signal generators have grown in capability and complexity in order to keep pace with the swift advances of vector modulated communications and advanced radar systems. One of the most critical performance parameters for these applications is phase noise. Purchasing an off-the-shelf...

Holzworth Instrumentation has an excellent reputation for its versatile product offering of phase coherent, ultra low phase noise RF synthesizers. What many engineers do not realize is that the RF synthesizer products have been a fundamental building block to Holzworth’s premier line of products. Customers are pleasantly surprised to...

First introduced in the late 1930s by a Bell Telephone Laboratories electrical communications engineer named W.H. Doherty and deployed in numerous broadcast radio station transmitters for years thereafter, the Doherty amplifier has been widely adopted in recent years by wireless infrastructure manufacturers seeking to squeeze every dB, W and...

Hittite Microwave has launched a new IF/Baseband Processing integrated circuit product line, introducing two new baseband compatible products that combine excellent performance with flexibility at a low cost. Both the HMC960LP4E dual digital variable gain amplifier and the HMC900LP5E dual programmable low pass filter meet the demand for a...

Epic Communications has developed a series of its next generation W-CDMA/HSPA power amplifiers (PA) that are specifically designed for 3G portable devices and mobile phones, and are compatible with industry leading 3G chipset solutions. This latest series of W-CDMA/HSPA PAs are designed specifically for the most popular UMTS/W-CDMA frequency...

6 to 18 GHz, 3 W Amplifier AML announces the immediate availability of a high power broadband amplifier model AML618P4202. This amplifier operates over 6 to 18 GHz with industry best DC to RF efficiency. Output P1dB is +35 dBm (3 W) minimum. Gain is 42 dB minimum with...

The next generation of wireless applications requires tunable or reconfigurable components to realize multifunctional RF systems. In current broadband RF systems, filtering dominates size and cost. 1,2 These filters are not tunable and hence limit the usable frequency range of most RF front-ends. An alternative to the use of...
