CMX90G702QF-R705

RF Amplifiers Overview

The CMX90G702QF-R705 is a low-power 50-ohm MMIC gain block amplifier from CML Micro, designed for operation within the 6 GHz to 18 GHz frequency range. It features a positive gain slope of +2 dB and delivers a typical gain of 11.5 dB with a noise figure of 3 dB. The device operates on a supply voltage of 2.7 V to 5 V, drawing 24 mA of current. Key performance metrics include a P1dB compression point of 11 dBm and an OIP3 of 21 dBm. It is housed in a compact VQFN-16 package suitable for surface mount installation.

RF Amplifiers Feature Summary

• Positive gain slope characteristic providing +2 dB variation across the operating band
• Low-power MMIC design optimized for wireless applications
• Integrated 50-ohm input and output impedance matching

RF Amplifiers Applications

• 5G infrastructure components
• Fixed Wireless Access (FWA) systems
• Ku-Band communication links
• X-Band radar or telemetry systems

RF Amplifiers Procurement Notes

Verify the specific suffix R705 against the manufacturer's latest datasheet to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with standard SMD reflow profiles for VQFN-16 packages. Confirm RoHS compliance status directly with the supplier documentation prior to finalizing procurement orders.

RF Amplifiers Selection Notes

Select this component when a low-noise, low-power gain stage is required for frequencies between 6 GHz and 18 GHz. The positive gain slope may necessitate external equalization if flat response is critical. Consider the 24 mA supply current for power budgeting in battery-operated or thermally constrained designs compared to higher-power alternatives.

RF Amplifiers Part Context

This part belongs to the CMX90 series of RF amplifiers from CML Microcircuits. The series includes variants such as the CMX90B702 for higher frequencies (23-29.5 GHz) and the CMX90A702 for Ka-band applications. The G702 variant specifically targets the lower microwave spectrum up to 18 GHz.
