Dear Sir,

Since RF1694A EOL, I would like to use BGSA14GN10  for substitution.  

currently, our L design RF1 connected 18nH, Rf2 connected 39nH, will it be a  risky for series resonance on these two path ? thanks.

Hello,

I'm not very experienced with RF frequencies. Need to design a single-transistor buffer. Input signal will be from an oscillator (NOT a 50 Ohm device - impedance not precisely known but assumed high), frequency will vary from a few MHz to ~1-2 GHz. Precise oscillator amplitude currently unknown but likely ~40mV to ~1V. Buffer output will route to a 50 Ohm measurement device. VCC likely small, either ~1.5V or ~3V. I was thinking of using the BFR340F. If anyone with experience can comment on this choice, or perhaps suggest something better, I would appreciate it. I am assuming that if I lay out a standard emitter-follower type circuit it will be a reasonable choice (input signal routes to base via capacitor to AC couple; voltage divider placeholder(s) to set DC voltage at base; optional resistor from VCC to collector; optional capacitor to ground from collector; resistor from emitter to ground, output through a capacitor from emitter).

Hello, 

Is it possible to connect two BGS18MA12 on the same MIPI bus?
If it rewrites the USID to the individual ID then it seems to be possible but I don't know if it is possible or not.

Best regards,
Nakamura

Hi All,

I am trying to figure out the nonlinear model for the BAR90-02ELS diode. The H-Spice works fine for forward bias but not for reverse bias. Anyone has the parameters to make a Caverly model that works for the reverse bias as well. I am trying to simulate it in AWR and these are the parameters I would need. 

Thank you

We want to design with Infineon BGA9H1MN9 (Mid- and High-Band Low Noise Amplifier with Gain Steps and MIPI Control) that the data sheet featured follows the MIPI RFFE 2.1 standard. Unfortunately, the datasheet itself did not show the MIPI protocol, formatting, and timing diagram.

I attempted to download the MIPI RFFE 2.1 from mipi.org, but the site won’t allow me to be a member to download it.

We want to interface and access the registers of the BGA9H1MN9 using an FPGA. We need the details on the protocol, formatting, and timing diagram. How and what are the steps to get the MIPI RFFE 2.1 standard? Else, if there is a separate document for the BGA9H1MN9 that details the protocol, formatting, and timing diagram, where can I get that?

Thanks in advance for any help given.
