🔍 Discover the Power of Precision!
The HiLetgo AD8310 RSSI High Speed High Frequency RF Output Log Detector is a versatile power meter module designed for a wide frequency range of 0.1 to 440 MHz. With a detection slope of +24 mV/dB and a dynamic range of -77 dBm to +18 dBm, it ensures accurate signal detection and measurement. Operating efficiently at 7-15V with a low current draw of 12mA, this module is perfect for both hobbyists and professionals looking to enhance their RF projects.

Good dynamic range and dB log tracking
I am using this for a log detector to drive a Tektronix 603 X-Y monitor scope. detector easily reaches a full 80 dB with a bit of headroom! I noticed some issues with other log detectors that are using different Analog Devices log amps withextended frequency coverage into the GHz range. Much less usable dynamic range and they had issues with oddnoise bursts near the device's baseline noise floor. This board is completely stable and results are consistent. Excellentfor use with a display or for driving a meter movement for a simple power level meter. Sweep generator is a HP-8333B; only issue is that the 8333B RF output is limited to about 6 dBm. The AD8310 needs another several dB toutilize its full log range.

No 52.3 ohm resistor on input
Analog Devices states that it is critical that the AD 8310 have a 52.3 ohm 1% resistor on the input to the device. This board only has a 100 ohm resistor. So I am going to have to buy some 52.3 ohm resistors and replace the 100 ohm unit.
