Product Overview
The ADL5545ARKZ-R7 is a broadband SOT-89 RF/IF gain block that provides approximately 24 dB fixed gain from 30 MHz to 6 GHz. Its input and output are internally matched to 50 Ω and the device includes bias control, simplifying the external RF network for a wide range of receiver and transmitter gain stages.
The exact balance of gain and current is notable: Analog Devices specifies 24.1 dB gain and 36.4 dBm OIP3 at 900 MHz while drawing only 56 mA from a 5 V supply. Compared with higher-current high-dynamic-range parts, the ADL5545 favors more gain per stage with a lower quiescent-current requirement.

Design Considerations
The 24.1 dB gain can reduce the number of cascaded amplifier stages, but it also raises the risk of downstream compression when strong blockers are present. Evaluate cascade gain and P1dB together rather than choosing the device solely for its fixed gain.
The 900 MHz linearity and noise values are reference conditions. For operation at several gigahertz, use the device curves and S-parameters at the actual frequency because gain, NF and OIP3 vary across the 6 GHz span.
