The CMX90G701 and CMX90G702 are positive gain-slope amplifiers that are suited to a range of radio frequency (RF) and wireless applications.
CML Microcircuits has released two new positive gain-slope amplifiers, the CMX90G701 and CMX90G702. Both amplifiers are suitable for a wide range of wireless applications operating in the 6 – 18 GHz frequency range. The amplifiers are capable of compensating the system losses thus eliminating the need for passive equalizers. The CMX90G701 and CMX90G702 are suitable for use in applications such as satellite communications, 5G fixed wireless access (FWA), microwave backhaul, radar, etc.
According to the company, the low-gain blocks have been developed using CML’s innovative SµRF MMIC design capability. Both devices deliver a small signal gain within the range of 9.5 – 11.5dB, a P1dB output rating of +10.0dBm, and a low noise figure of 3dB. 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, whereas, the CMX90G702 offers a +2dB gain slope for applications requiring higher gain-slope compensation.
“Following on from our earlier release of positive gain-slope amplifiers targeting the sub-7 GHz markets, the CMX90G701 and CMX90G702 Low Power Gain Blocks move further up the RF spectrum to 6-18GHz. These devices employ CML’s advanced SµRF design capability and add to our growing portfolio of positive gain-slope amplifiers. These devices address the growing market requirement for high-performing mmWave devices in a range of applications including microwave backhaul, radar, and satellite communications ”, said Arwyn Roberts, Product Manager for RF & mmWave. The CMX90G701 and CMX90G702 are now available, joining the CMX90G301 and CMX90G302 low-power amplifier range. Future products in the SµRF family will include a range of PAs, LNAs, Gain Blocks and FEMs, employing high-performance GaAs and GaN technologies.”
Both the CMX90G701 and CMX90G702 Gain Blocks offer a high level of integration, which reduces the count and cost of external components, thus reducing the size of the PCB while also reducing the time and resources required for the design and development of the product. Both devices can operate over a wide variety of supply voltage range from 2V to 5V. Moreover, the RF ports of each device are internally matched to 50 Ω, supporting rapid product development cycles, particularly for mass-market applications.
