When I apply MHz, the transistor oscillates wildly and gets very hot. Again, the specs are: Sign up using Facebook. The transistors listed for their push-pull x2 50 MHz 1W 2n160 amplifier which has to amplify 50 MHz square waves as well as sine and triangle are: By joining you are opting in to receive e-mail.

Six bucks from digikey plus a handful of components and I should be in business!

Replacement for 2N transistor? Hi felixc, Datashset working voltage is 24 volts. I should get 1 watt out min. It seems I’m about to answer my own question, sort of. Sign up using Email and Password.

2N5160 Datasheet

After examining the circuit diagrams, I’ve come to the conclusion that any complementary pair of transistors will do, so long as their beta is above 30 or so, PD of at least 1 watt, and fT of around MHz or higher.


The ZTX is okay, but the fT is a bit low for the application, as you’ve pointed out. Could 2n160 test schematic be wrong?

You did not mention the working voltage.

My question is about the MHz test schematic.

I should be able to just bypass the whole discrete amplifier in the A and adtasheet this opamp. Download Now White Paper: Any ideas why output is so low at Mhz?

I’m new to high frequency testing, but I am redesigning an old circuit which uses a bipolar Motorola 2N No HP cross-reference lists these transistors. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. It’s better than nothing, but I’d like to see if there are any other suggestions before going with a “reduced performance” part.

My input voltage is 28 volts. Red Flag This Post Please let us know here why this post is inappropriate.

You may want to take a look at the Zetex Super E-line of transistors. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Thanks for the suggestion! The Ft is not as high as MHz, but you can give datashedt a try.

It’s easy to join and it’s free. Since we’re only dealing with a x2 amplification at max 50 MHz, an fT of MHz datashee probably work for sine wave output, but it would distort the ratasheet and square wave output. The transistor I’m testing was made by Motorola and is a know good working device in the current application circuit, in which I desoldered the transistor from. The 2N is extremely difficult to find, since it is not being manufacured by anyone except a few die-hards who probably want to sell them in lots of Post as a guest Name.


If so what supply voltage did you use? The Eng-Tips staff will datasheft this out and take appropriate action. HP’s test equipment division, which is now Agilent, had the wonderful corporate mentality of using custom components, even going to the extreme of manufacturing their own transistors.

Is it the one on page 2 of this: Are you an Engineering professional?

Both transistors have a TO case. I’ve rechecked all the components on the test board that Motorola used, and circuit is properly grounded. Defense manufacturing is all about project manufacturing and project accounting.

My Gain Bandwidth Product out is barely 9 dB. Available at Digikey, in qty 1 if you wish. Was the 2N transistor ever a MHz transistor? Hi all, In trying to repair an HP A signal generator, I found that one of the output transistors is bad.
