The TriQuint TGA2527-SM is very linear and operates from 12.5 to 15.5 GHz, while the TGA4539-SM operates from 28 to 30 GHz.
The TGA2527-SM offers very high efficiency, typically 20% greater than competing devices, at its saturated power level (Psat) of 31.5dBm.
Both devices have P1dB RF power output of 30dBm (1W) and are housed in cost-efficient 5 x 5mm QFN packages; both solutions are RoHS compliant and have onboard power detectors for monitoring purposes. They are designed to be extremely easy to integrate into RF circuits and are highly rugged.
The TGA2527-SM can handle an RF input power of 24dBm CW and the TGA4539-SM can handle 22dBm.
The new TGA2527-SM and TGA4539-SM are both in production. Samples and fully-assembled evaluation fixtures are available.
RFMD reveals “industry- best” GaAs/InGaP WiFi FEMs
Designed for both “chip on board” and “system- in-package” (SiP) implementations, both product families employ the firm’s gallium arsenide pHEMT and gallium indium phosphide HBT technology and operate over a wide range of operating voltages. The highly integrated FEMs significantly reduce external component count outside the core WiFi chipset
RF Micro Devices has revealed four high- performance front end modules (FEMs) for next generation WiFi applications.
The RFFM8200, RFFM8500, RFFM8202, and RFFM8502 are highly integrated FEM solutions covering multiple WiFi standards and frequency bands, particularly IEEE802.11n and the emerging 802.11ac specification. RFMD’s FEMs achieve excellent linear power and dynamic error vector magnitude (EVM) performance in support of the newest reference designs from the leading WiFi chipset providers.
The WiFi market is growing rapidly, driven by increasing consumer demand for access to mobile broadband data and the expanding operator requirements for data offload to accommodate increased cellular and cable network services. By 2015, it is projected the WiFi FEM mobile/ embedded and consumer premises equipment markets will exceed $1.8 billion.
Rohan Houlden, general manager of RFMD’s wireless connectivity business unit, says, “RFMD’s newest WiFi front end modules demonstrate industry-leading performance and are aligned with the industry’s leading WiFi chipset providers on their most anticipated reference designs. By achieving superior linearity and dynamic EVM, RFMD’s WiFi front end modules enable the proliferation of mobile broadband connectivity across an ever-expanding range of growth markets, including smartphones, tablets, notebooks, ultra-books, PCs, TV/video, e-readers, gaming, and automotive.”
Dynamic EVM is a critical design specification for high data rate WiFi systems. While competitor solutions have traditionally measured static EVM performance, RFMD says its FEMs achieve superior dynamic EVM to deliver best-in-class real-world WiFi system performance. This enables optimum data throughput at increased operator range, current savings through optimal transmit and receive speeds, and an enhanced user experience during video streaming, gaming, and other high
