Feature

●Meanwhile, the AD831 provides a 3D intermodulation intercept point with +24 dBm to deliver the power consumption of a -10 dBm local oscillator, and it can be improved, because there is no high power local oscillator and no corresponding shield and isolation issues.
●Mixers are designed to be powered from a single power source. RF, IF and local oscillators have DC insulated capacitors for ease of use. The operating frequency of the RF and local oscillator input is up to 500MHz. IF output is single-ended bolter.
●The 250 MHz output bandwidth uses a single resistor connected between pin out and feedback. This amplifier has low DC offset characteristics, so it can be used in DC bonded applications such as DC baseband frequency conversion.
●AD831 is a single chip mixer suitable for low distortion, wide dynamic range, RF-IF down conversion in high and ultra-high frequency receivers, a second mixer at digital mobile radio base stations, DC baseband conversion, straight modulation, and
●If the mixer output amplifier and good source impedance exists, the mixer SSB noise index is 10.3dB at 70MHz. Unlike passive mixers, AD831 has no insertion loss, external duplexer or passive termination.


Description

Function: 1 The AD831 is a single chip mixer suitable for RF-IF down conversion in low distortion, wide dynamic range, high and ultra high frequency receivers, a second mixer at digital mobile radio base stations, DC base band conversion, straight modulation and demodulation, and doppler shift detection in ultrasonic imaging.
2. Meanwhile, the AD831 provides a 3-dimensional intercept point with +24 dBm local oscillator power consumption and high power local oscillator without the corresponding shield and isolation issue, which can be improved compared to passive mixer systems. Reduce performance, system costs
3 Mixers are designed to be powered from a single power source. RF, IF and local oscillators have DC insulated capacitors for ease of use. The operating frequency of the RF and local oscillator input is up to 500MHz. IF output is a single end voltage output.
4 The 250 MHz output bandwidth uses a single resistor connected between pin out and feedback. This amplifier has low DC offset characteristics, so it can be used in DC bonded applications such as DC baseband frequency conversions and orthodonal amplition modulation.
5 Mixer SS when mixer output amplifier and good source impedance exist.
