Richardson RFPD announces HEMT, front-end module, synthesizer
Geneva, IL. Richardson RFPD this month has announced several new products that it is carrying and for which it is providing full design support. The products include a GaN on SiC depletion-mode HEMT from NXP Semiconductors, a 2.4-GHz front-end module from Skyworks Solutions Inc., and a new wideband synthesizer from Analog Devices Inc.
NXP’s AFG24S100HR5 is a 125-W CW RF power GaN transistor that operates from 1 MHz to 2,700 MHz and includes input-matching for extended bandwidth performance. With its high gain and high ruggedness, this device is suitable for a range of CW, pulse, and wideband RF applications, including public mobile radios, ISM (industrial, scientific and medical), wideband laboratory amplifiers, and wireless cellular infrastructure.
Key features of the AFG24S100HR5 include an operating voltage of +50 VDC; gain (in a 2,500-MHz narrowband test circuit) 16.0 dB CW, 18.0 dB pulse; efficiency (in a 2,500 MHz narrowband test circuit) of 64.2% CW, 66.8% pulse; and thermal resistance of 0.86°C/W. It offers a > 20:1 VSWR and comes in an NI-360H-2SB ceramic flanged package.
The new device is part of the lineup of NXP RF power transistors for ISM and broadcast applications that are available from Richardson RFPD. These devices are designed to simplify the use of solid-state RF in high-powered ISM applications at frequencies from 1 to 600 MHz, as well as applications in the 915-, 1,300- and 2,450 MHz frequency bands for FM radio and VHF and UHF TV broadcast. For additional information on these products, see pages 24–25 of the NXP RP Product Selector Guide.
Front-end module
The Skyworks SKY66112-11 is a high-performance, fully-integrated RF front-end module (FEM) designed for ZigBee, Thread and Bluetooth Smart applications. Designed for ease-of-use and maximum flexibility, the new device provides an integrated inter-stage matching and harmonic filter as well as digital controls compatible with 1.6-V to 3.6-V CMOS levels. It maximizes battery life while simultaneously increasing transmission range with improved power.
The SKY66112-11 integrates a power amplifier with up to +21 dBm output power, a low-noise amplifier with 2-dB noise figure and bypass path, and antenna diversity switching for all modes. It is designed for a range of Internet of Things applications, such as in-home appliances, smart thermostats, smart lighting, sensors, range extenders, and other IoT devices.
Additional key features of the SKY66112-11 include a frequency range of 2,400 to 2,483 MHz, a single-ended transmit/receive interface, an on/off switch time of < 800 ns, a supply range of 1.8 V to 3.6 V, and a sleep-mode current < 1 μA typical. No external bias resistor is required. The device comes in a 22-pin, 3.5 mm x 3.0 mm x 1.0 mm MCM package.

Wideband synthesizer
The Analog Devices ADF4356 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. A series of frequency dividers at another frequency output permits operation from 53.125 MHz to 6,800 MHz. The ADF4356 has an integrated VCO with a fundamental output frequency ranging from 3,400 MHz to 6,800 MHz.
