Buy AD8309 500MHZ 100dB Dynamic Amplifier with Limiting Output for FSK PSK Demodulation factory direct price
Description:
AD8309 is a 500 MHz detection logarithmic amplifier based on continuous detection technology, suitable for received signal strength indicator (RSSI) and phase detection in cellular base stations, and other radio transceiver applications.
The device provides a dynamic range of 100 dB, an accuracy of ±0.4 dB in the middle 80 dB range, and an operating frequency of up to 500 MHz. The logarithmic output is proportional to the logarithm of the input signal and can provide a 0.4 V to 2.5 V DC signal within a 100 dB input range. The device also provides a limiter output that can amplify the input signal by 100 dB and provides a stable limiter output with a maximum phase deviation of ±100 ps. This limiter output is useful for demodulating FSK and PSK modulated signals.
Specification:
Power supply voltage: 55V DC (within a typical current value of 20mA);
Complete multistage logarithmic-limiting IF amplifier
Dynamic range: 100 dB -78 dBm to +22 dBm (Re 50 O)
Programmable limiter gain and output current
Differential output to 10 mA, 2.4 V peak-to-peak
Total gain: 100 dB, bandwidth: 500 MHz
Frequency range: 5MHZ-500MHZ;
Constant phase (typical delay deviation: 680 ps)
Power-on time: 500 ns, sleep current: <1 mA
RSSI scaling does not change with temperature and power supply voltage: slope: 20 mV/dB, intercept: -95 dBm
RSSI linearity: ±0.4 dB (to 200 MHz)
Single power supply: +2.7 V to +6.5 V
Current: 16 mA (typical value)
Input and output interface: SMA outer screw inner hole
Product size: 50 x 50 x 9mm

I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited
After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.
This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.
