CML medium power amp targets repeaters and small cells
CML Microcircuits has announced the availability of the CMX90A702 28GHz 5G medium power amplifier (MPA). It uses CML’s SmicroRF RFIC/MMIC design capability, and targets 5G mmWave infrastructure applications, including repeaters, small cells, customer-premises equipment (CPE), passive antenna arrays and 5G backhaul applications.
Operating in frequency range 2 (FR2) from 26.5 to 29.5GHz, the linear CMX90A702 supports 5G new radio (NR) bands n257 and n261, with a 400MHz 64-QAM carrier signal achieving EVM of less than four per cent at 18dBm mean power.
The device delivers +25dBm (0.3W) of output power at the 1dB gain compression point with power added efficiency of 26 per cent to ensure power efficiency, the company claimed.
RF ports matched to 50 Ohms offer ease of use, supporting rapid product development cycles and high-volume manufacturing.
“The CMX90A702 medium power amp addresses the growing market requirement for high-performing mmWave devices and is designed to support rapid product development cycles,” said Mark McCabe, managing director, CML.
This device is the first in a planned range of products to be developed using CML’s SmicroRF design capability. The SmicroRF capability will help to reduce development cycle times and gain access to emerging markets such as 5G, satcom and IoT. Future products in the SmicroRF family will include a range of PAs, LNAs, gain blocks and FEMs, all employing high performance GaAs and GaN technologies, said the company.
