Two amplifiers meet RF and wireless range for satcom and 5G FWA
Two low power, positive gain-slope amplifiers by CML Microcircuits, the CMX90G701 and CMX90G702 have positive gain-slopes of +1dB and +2dB respectively. They also have an operating frequency range of 6.0 to 18GHz (C, X, Ku-band). The two devices are suitable for a range of RF and wireless applications including microwave backhaul, radar, satellite communications, 5G fixed wireless access (FWA) and VSAT, said the company.
Developed using CML’s SµRF MMIC design capability, these general-purpose gain blocks can also be used to eliminate passive equalisers by compensating for system losses across the operating frequency range.
Both devices are fabricated using GaAs pHEMT process technology to achieve an optimal combination of high linearity, low noise and low DC power consumption. The CMX90G701 has +1dB positive gain-slope, while the CMX90G702 offers a +2dB gain-slope for applications requiring higher gain-slope compensation. Both amplifiers deliver a small signal gain within the range of 9.5 to 11.5dB, a P1dB output rating of +10.0dBm and a low noise figure of 3dB.
The CMX90G701 and CMX90G702 Gain Blocks are designed with a high level of integration to minimise external component count and reduce PCB footprint. The cascadable gain blocks eliminate the need for passive equalisation circuits within the system design. The on-board active bias circuit means the devices operate over a wide supply voltage of 2.0 to 5.0V, with a typical current of 22mA. The RF ports of each device are internally matched to 50 Ohm, claimed to support rapid product development cycles, particularly for mass market applications.
The CMX90G701 and CMX90G702 are available now, joining the CMX90G301 and CMX90G302 low power amplifier range. Future products in the SµRF family will include a range of power amplifiers, LNAs, gain blocks and FEMs, employing GaAs and GaN technologies, confirmed CML.
CML Microcircuits designs, develops and supplies low power analogue, digital and mixed signal semiconductors for telecommunications systems globally.
The company’s wide and varied portfolio means that its devices are used in an extensive range of industrial and commercial products for licensed and unlicensed wireless voice and data systems.
In addition to the established range of devices, CML Microcircuits is able to offer a bespoke service which includes design assistance, advice and technical support.
