It offers three 8GHz NPN parts and two 5.5GHz PNP parts in a single array. https://www.renesas.com/us/en/document/dst/hfa3046-hfa3096-hfa3127-hfa3128-datasheet?r=494216 Two of the NPN parts could make up my emitter-coupled monostable, and the two PNP parts could level shift the output. The Renesas website offers Spice models for both the NPN and the PNP transistors, which one could plug into an LTSpice simulation, at the cost of making it look too messy for the more sensitive designers to be able to look at. -- Bill Sloman, Sydney -- This email has been checked for viruses by Norton antivirus software. www.norton.com
