Ultra-wide bandwidth RF mixers offer unparalleled flexibility
Integrated Device Technology has introduced its VersaMixer family of ultra-wide bandwidth RF mixers, offering unparalleled flexibility through a combination of features suitable for today’s advanced RF-based communications systems. Delivering IDT’s hallmark high linearity, the VersaMixer F1192 and F1792 devices are designed for any radio system requiring high performance and low power operating between 400MHz and 3800MHz.
The F1192 is a dual-channel RF mixer, while the F1792 is single-channel. The devices offer configurable-gain operation for use in a wide array of radio card applications, including 2G-to-5G multimode remote radio units, backhaul systems and public safety infrastructure. Coupled with ultra-wide bandwidth, this gives radio system designers the flexibility to optimize the receive system gain, noise, and linearity budget for virtually any application. Low power consumption — typically just 835mW total for two channels — supports high-density PCB layout design in modern remote radio units and small cells.
Unlike competitive offerings, the VersaMixer devices function over the entire operating bandwidth without any changes in external components. This means that a single bill of materials can support various RF and IF operating bandwidths, easing integration into different systems, and keeping a check on costs and time to market.
“This VersaMixer family continues IDT’s trend of bringing innovative design technology to the markets we serve, and cements our RF leadership role for mixers, DSAs and VGAs targeting infrastructure and other high-performance applications,” said Chris Stephens, General Manager, IDT’s RF division. “The unique combination of high linearity, ultra-wide bandwidth, adjustable gain and extremely low power in one device has been enthusiastically received by early key customers.”
Based on IDT’s FlatNoise technology, the configurable gain feature keeps the noise figure relatively unaffected as the gain setting is reduced and the Input IP3 and Input P1dB are actually increased. Gain is controlled via 2 parallel pins with settling times of <100 ns, allowing for dynamic adjustment of gain to maximise performance 'on-the-fly' if the radio designer desires.
