AD835 Mixing Broadband Modem Precision Analog Multiplier with Rear Stage Op Amp Four Quadrant Analog Multiplier
Parameter
| Name | AD835 Multiplier with Rear Stage |
| Size | 50mm X 50mm |
| Supply voltage range | ±5V |
Modulation Type: Multiplier
Multiplication Quadrant: Four quadrants can be multiplied and the port is set aside
Bandwidth: 250MHz
Input and output impedance: 50 ohms
Performance: The AD835 module can be used as a four-quadrant multiplier. However, the X1 and Y1 are configured by default in the module introduced in this store, and can be used as a multiplier to double the frequency. Performance is really good, all kinds of signal modulation, waveform stability. Our AD835 module also has a wideband amplifier at the output stage, which can amplify the modulated signal output from the AD835 again to meet some high-amplitude output requirements.
Highlights
Using a large number of power supply decoupling capacitors, the post-stage output also adds a single op amp as an amplification process, making up for the disadvantages of the AD835's attenuation.

Input signal 10MHz output 20MHz
Input signal 50MHz output 100MHz
The input signal is 100MHz and the output is 200MHz. It can be seen that the harmonic component is relatively heavy when the output is 200MHz. It is recommended to add a low-pass filter.
