So there was a miswire in the negative bias to the diodes, fixed that - the response to the output of the OPA847 looks fine, not sure this is the shape you want.Those diodes divider bias networks are causing that lower frequency shift and reducing the…
Hi Michael,
I still was not able to solve 20MHz (sometimes 17MHz) oscillation. I tried the following things:
1. Putting the 10uF Aluminium electrolytic capacitor.
2. Removing 0402/10pF - Ceramic cap and replacing them with 0603/0.1uF Ceramic cap.
3.Using…
Part Number: OPA847 Hello
I have the same problem as mentioned in the thread linked to this post.
The model of the OPA847 that I imported into ADS doesn't work, apparently due to syntax errors in the model of the switches. I get the following error message…
Part Number: OPA847 Hi,
In the OPA847's datasheet is mentioned that the amplifier is stable down to gains as low as +12 V/V.
Is it possible to operate with a voltage gain of 6.3 V/V (to obtain Gp = 10dBm with 50 ohm source and load)? In what conditions…
Part Number: OPA847 Hi;
I am currently seeking a pre-configured model for the OP847 that works on ORCAD Pspice. Previously I had no issue with any TI models however, this particular model has some instruction that is not clear on how to revise the model…
