Product Overview
The ADL5602ARKZ-R7 is a 20 dB internally matched RF/IF gain block covering 50 MHz to 4 GHz. Analog Devices positions it for high dynamic range, combining 42.0 dBm OIP3 with 19.3 dBm P1dB at 2 GHz while maintaining a 50 Ω input and output interface.
Its selection profile differs from higher-gain but lower-linearity gain blocks. The ADL5602 uses 89 mA from a 5 V supply to deliver strong large-signal performance across a broad RF range, making it more suitable when blocker tolerance and cascade linearity matter more than minimizing dc current.

Design Considerations
The 42 dBm OIP3 value is tied to the documented 2 GHz condition. Cascade analysis should use the performance curve at the actual operating frequency because linearity and gain move across the full 4 GHz span.
The SOT-89 package is thermally efficient, but 5 V × 89 mA still creates a substantial dc heat load before RF output power is considered. Verify board copper and junction temperature for continuous high-ambient operation.

For a wider-frequency RF/IF gain block choice in a SOT-89 package, compare ADL5611ARKZ-R7. Analog Devices specifies 50 MHz to 4 GHz and 20 dB fixed gain for ADL5602, versus 30 MHz to 6 GHz and 22.2 dB nominal gain for ADL5611. Recheck noise figure, compression, bias current, frequency-specific gain and board matching before selecting either device; do not assume drop-in interchangeability.
