The biasing may need to be adjusted for different supply voltages. Delivery Options see all. Additional information is0. Depending on the frequency of operation, the gain will be from 15dB to 30dB – higher gain at lower frequencies. I have the Motorola Selection Guides going back to and it doesn’t show up. Maximum Power Dissipation Pd: No abstract text available Text: TheMAX including a simplified package model.

This device can replace many 40xxxx, 3nxxx and MFExxx series dual-gate mosfets. The input stage is not modeled since the electrical model is not considered an adequate representation for the analysis of the input optical signal.


You are bidding for TWO pieces. You won’t find cheaper prices anywhere! There seems to be a problem serving the request at this time. John, So based on the specs that I provided, you think any one of those you listed will work?


Buying Format see all. This file provides some background to how the model files areParameters The bipolar transistor circuit model used by the SPICE software is a modified version of the. The model is believed accurate.

The no- signal AGC bias should be around 4- 5V – check the data sheet. Date code is year week 6.

It’s amazing what one can accumulate over decades. See detailed photos of transistors. Within 2 miles 5 miles 10 miles 15 miles 20 miles 50 miles 75 miles miles miles miles miles miles miles miles miles of.

This is for 2 pcs of the 3SK80 Transistor.

BF MOSFET Datasheet pdf – Equivalent. Cross Reference Search

This is for 1 pc of the 3SK39 Transistor. Additional selectivity or filtering may be required to reduce the wideband noise at the output. Pls allow weeks for delivery. Please provide a valid price range. They’re cheap and readily available at Rat Shack. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at It isincluding this notice for that purpose only. Datasheeh anyone has info on this mosfet, or knows of a sub that’ll work, or if I can even put two together or not ,please respond.

Best deal on eBay! Simplified input package model and inputMaxim MAX 2. Potentiometer Questions Started by norbss Yesterday at Additional RF selectivity may be implemented by using a multi- section bandpass filter instead of the single tuned circuit that is shown. Skip to main content. Replacement Transformer Started by ncag Today at 7: Hard to find parts for your electronic project.


The model is believed accurate but no condition or warranty as to its merchantability or fitness. The output stage is not modeled since the electrical model is not. Spice Net List Extraction 3. Keep the input and out circuits apart and if necessary, put a screen between the two to ensure stability.

Gold lead and very difficult to find. It’s a two gate N channel in a TO case.

With the rare exception of a commodity-type fungible item all are alike or equivalent or a generic picture, you get the actual item pictured and described. During tests, some UHF instability was noted which did not seem to be bf90 affected by circuit layout or decoupling so a ferrite bead was put onto the emitter leg of the NPN device which cured the problem.

Perhaps the schematic has a typo.
