Replacement verdict
Compatible functional replacement candidate
The ADRF5024BCCZN and ADRF5025BCCZN are functionally comparable absorptive SPDT RF switches from the same manufacturer and product family, sharing a common LGA-20 footprint and overlapping supply and control interfaces. The primary distinction is the specified frequency range, so the ADRF5025BCCZN can serve as a functional replacement for the ADRF5024BCCZN only when the application's operating band falls within the lower-frequency range supported by the ADRF5025BCCZN; verification of the target band against the datasheet limits is required before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADRF5024BCCZN | ADRF5025BCCZN | Why it matters |
|---|---|---|---|
| Frequency Range | 100 MHz to 44 GHz | 9 kHz to 44 GHz | The lower frequency limit determines whether the switch can be used for baseband, IF, or low-frequency signal routing; the ADRF5025 extends operation down to 9 kHz. |
| Insertion Loss (typical) | 1.5 dB at 40 GHz | 1.3 dB at 40 GHz | Lower insertion loss directly improves signal chain budget and noise performance in RF front-end designs. |
| Isolation (typical) | 35 dB at 40 GHz | 38 dB at 40 GHz | Higher isolation reduces leakage between channels and ports, which is critical for switching and TDD applications. |
| Input P1dB (typical) | 27 dBm | 29 dBm | P1dB defines the maximum linear power handling; higher P1dB allows the switch to handle larger signals without compression. |
| Input IP3 (typical) | 50 dBm | 53 dBm | Higher IIP3 indicates better linearity, reducing intermodulation distortion in multi-carrier systems. |
| Switching Time (rise/fall, typical) | 1.5 µs | 1.1 µs | Faster switching enables quicker TDD turnaround and higher-speed signal routing in time-sensitive systems. |
| Supply Voltage | 3.3 V | 3.3 V | Matching supply voltage allows drop-in compatibility with the same power rail design. |
| Control Logic | CMOS/TTL compatible | CMOS/TTL compatible | Identical control interface ensures the same digital driver circuitry can be reused. |
| Package | 20-lead LGA (BCCZN) | 20-lead LGA (BCCZN) | Same package footprint enables board-level drop-in replacement without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure equivalent environmental robustness for industrial and commercial applications. |

Frequently asked questions
What are the key differences between the ADRF5024BCCZN and ADRF5025BCCZN?
Both are absorptive, non-reflective SPDT RF switches from Analog Devices in a 20-terminal LGA package. The primary difference is the frequency range: the ADRF5024BCCZN operates from 100 MHz to 44 GHz, while the ADRF5025BCCZN operates from 9 kHz to 44 GHz, extending low-frequency coverage down to the audio/ultra-low RF range.
Are the ADRF5024BCCZN and ADRF5025BCCZN pin-compatible?
Yes. Both devices are offered in the same 20-terminal LGA package (CC-20-3) with identical pin assignments, allowing a common PCB footprint. Designers should still confirm the land pattern and thermal considerations against the respective datasheets.
What is the operating frequency range of each device?
The ADRF5024BCCZN is specified from 100 MHz to 44 GHz. The ADRF5025BCCZN is specified from 9 kHz to 44 GHz, making it suitable for applications requiring operation below 100 MHz.
What control interface do these switches use?
Both the ADRF5024BCCZN and ADRF5025BCCZN use a single positive control voltage (VCTRL) with a CMOS/TTL-compatible logic interface to select between the two RF paths, and both require positive and negative supply rails (VDD and VSS).
What are the supply voltage requirements for these switches?
Both devices operate with a positive supply (VDD) and a negative supply (VSS). Refer to the respective Analog Devices datasheets for the exact specified voltage ranges and current consumption, as these must be observed for reliable operation.
Are these switches absorptive or reflective?
Both the ADRF5024BCCZN and ADRF5025BCCZN are absorptive (non-reflective) designs, meaning the unselected RF port is internally terminated to 50 ohms, which improves return loss and reduces reflections in switched RF paths.
Which applications typically require the ADRF5025BCCZN over the ADRF5024BCCZN?
The ADRF5025BCCZN is preferred when operation below 100 MHz (down to 9 kHz) is required, such as in baseband, IF, or low-frequency RF signal routing. For applications operating only above 100 MHz, the ADRF5024BCCZN provides equivalent high-frequency performance to 44 GHz.
