The ADL5721 is a narrow-band, high performance, low noise amplifier targeting microwave radio link receiver designs. The monolithic silicon germanium (SiGe) design is optimized for microwave radio link bands ranging from 5.9 GHz to 8.5 GHz. The unique design offers a single-ended 50 Ω input impedance and provides a 100 Ω balanced differential output that is ideal for driving Analog Devices, Inc., differential downconverters and radio frequency (RF) sampling analog-to-digital converters (ADCs). This low noise amplifier (LNA) provides noise figure performance that, in the past, required more expensive three-five (III-V) compounds process technology to achieve. This LNA uses a band switch feature to allow the input P1dB and noise figure to trade off for optimum system performance.
The ADL5721 and ADL5723 to ADL5726 family of narrow-band LNAs are each packaged in a tiny, thermally enhanced, 2.00 mm × 2.00 mm LFCSP package. The ADL5721 and ADL5723 to ADL5726 family operates over the temperature range of −40°C to +85°C.
Applications
- Point to point microwave radios
- Instrumentation
- Satellite communications (SATCOM)
