Description
The AD8318ACPZ-WP is a demodulating logarithmic amplifier that is designed to accurately convert an RF input signal to a corresponding decibel scaled output voltage. It is primarily used in measurement or controller mode. This device is capable of maintaining accurate log conformity for signals of 1 MHz to 6 GHz and provides useful operation up to 8 GHz. The input range is typically 60 dB (re: 50 Ω) and maintains an error of less than ±1 dB. It has a 10 ns response time that enables RF burst detection to beyond 45 MHz. Additionally, the AD8318 provides unprecedented logarithmic intercept stability across a broad range of ambient temperature conditions.
Specifications and features
- Wide bandwidth: The AD8318 has a wide bandwidth that ranges from 1 MHz to 8 GHz, making it suitable for a wide range of applications.
- High accuracy: It has a high accuracy of ±1.0 dB over a 55 dB range (f < 5.8 GHz).
- Stability over temperature: The device maintains stability of ±0.5 dB over a broad range of ambient temperatures.
- Pulse response time: The AD8318 has a pulse response time of 10 ns/12 ns (fall/rise).
- Integrated temperature sensor: The device includes an integrated temperature sensor that outputs a 2 mV/°C slope for additional system monitoring.
- Small footprint CSP package: The AD8318 is fabricated using a high-speed SiGe process, allowing for a small footprint CSP package.
- Power-down feature: It consumes <1.5 mW of power at 5 V when the device is disabled.
- Single-supply operation: It requires a single supply of 5 V at 68 mA for normal operation.
Application Scenarios
- RF transmitter PA setpoint control and level monitoring: The AD8318 is used in RF transmitter PA setpoint control to maintain the output signal within the desired range. It is also used in level monitoring applications where the signal strength is required to be within a specific range.
- RSSI measurement in base stations, WLAN, WiMAX, and radar: The AD8318 is also used for RSSI (Received Signal Strength Indication) measurement in base stations, wireless local area networks (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), and radar.
Comparison
Advantages- The AD8318 has a wide bandwidth that ranges from 1 MHz to 8 GHz, making it ideal for a variety of applications.
- This device maintains high accuracy with an error of less than ±1 dB over a 55 dB range (f < 5.8 GHz).
- It maintains the stability of ±0.5 dB over a broad range of ambient temperatures, which is useful in many applications.
- The AD8318 is fabricated using high-speed SiGe process, so it has a small footprint.
Disadvantages- This device consumes relatively high power at 5 V, requiring a 68 mA current for normal operation, which could be a disadvantage in battery-powered applications.
