Can you please share the test results (P1dB, Gain & RL) for HMC788A with MMZ0603S102ET000 for frequency range 2GHz to 6GHz?
We designed the Eval board for HMC788A by ourselves, but only got 8dB gain at 8GHz while should be 12+dB at datasheet. What is the concern for the PCB design? Can let me know the detail design information of the PCB structure?
Hello, I have an issue with wide band amplifiers I have built using the HMC788A biased via a TCBT-14R+ (minicircuits).
Power supply is 5V (via a 1.8ohm resistor to the TCBT-14R+ Bias Tee )
Input connected to antenna via a series 10nF capacitor only…
The gain flatness vs frequency of HMC788A-EP (Enhanced Product) looks better than the commercial grade (HMC788ALP2E). Are the two devices not the same but with different qualification.
My customer are considering to use HMC408LP3E and HMC788ALP2E.
And they have some issues to darw PCB artwork related desiding size of pattern.
Please refer below questions and let me know your opinions.

HMC788A has too much gain in my LO signal chain and I believe that it is causing excessive dc offsets in my IQ demodulator. Is there an easy to reduce the gain to around 7 or 8 dB?

The HMC788A or equivalent in a different frequency range( look at the RF Amplifier product value ) could be used .
I downloaded s-parameters for HMC3113 & HMC788A. Are these S-parameter values measured with one Amplifier or a batch of amplifiers (i.e. averaged)?
Yes, take a look at the HMC788A. You can order samples through the product page below.http://www.analog.com/en/products/amplifiers/rf-amplifiers/hmc788a.html#product-overview
