CML Micro launch the CMX90B701/702 low current mmWave gain blocks

31 March 2023

The new additions to the SµRF product family are the latest to leverage CMLs innovative RFIC/MMIC design capability, offering low current and low noise performance in the 17 – 23 GHz and 23 – 29.5 GHz ranges respectively.

Maldon, Essex, UK – CML Microcircuits, world-leading developers of analogue, digital and mixed-signal semiconductors for global telecommunications systems, today announced the availability of the CMX90B701 and CMX90B702 Low Current/Noise Gain Blocks. These devices are the latest additions to CML’s innovative SµRF product family and continue CML’s push into the higher frequency ranges of mmWave and beyond.

Both the CMX90B701 and the CMX90B702 offer an optimal balance between output power, linearity, and noise with a typical P1dB output figure of +7.5 dBm, an IP3 output of +17.5 dBm and a noise figure of 4 dB. Thanks to an innovative dual-bias mode, these low-current devices can be set to operate at either 10mA or 15mA from a single positive supply rail ranging between 3 and 5 V. The high maximum operating temperature of the gain blocks, (105 °C), enables them to be used in wireless infrastructure and compact transceiver applications.

“With the CMX90B701 and CMX90B702, CML continue to prioritise simplicity for the designer” said Arwyn Roberts, RF Product Manager. “With input and output ports matched to 50Ω, these devices can be easily plugged into the RF system with minimal external components and offer an optimal balance between low power consumption and performance.”

Employing GaAs pHEMT technology, the gain blocks are ideally suited to applications such as 5G mmWave infrastructure, Ka-band satcom and microwave backhaul, where dynamic market conditions demand mass-market, cost-effective solutions.

The CMX90B701 and CMX90B702 are the latest products to leverage CML’s significant investment in high frequency RFIC/MMIC design capability, adding to the rapidly expanding SµRF portfolio, which includes a range of PAs, LNAs, Gain Blocks and FEMs, all based on GaAs and GaN technologies.
