Hi,
I am looking for an alternate part # of u25 and u13 - the original part # is
MGA81563TR1G is a rf amplifier
in my hackrf I damaged both with static antenna charge

Subject: [Hackrf-dev] Hackrf One output impedance
Message-ID:

What is the output impedance when transmitting at 147.42 MHz with and
without the output amplifier?
I?ve built an RF amplifier to boost the output about 26 dB, but with no
signal it oscillates. The data sheet suggests it is probably due to an
impedance mismatch between the Hackrf and the amp. So, can anyone say
definitely the impedance of the Hackrf?
Thanks,
Jake

The output impedance is 50 ohms.
