Have you seen the new national advertising campaign where Freescale (formerly Motorola) is using big name celebrities to sell their cellular base station power transistors? Scarlett Johansson and Ashton Kutcher are up on a tower along with man-and-woman-on-the-tower smartphone users discussing how much better their phones work now that the service provider switched to base transceiver stations (BTSs) that use Freescale LDMOS RF power transistors. Of course you haven't seen the ad because it would never be produced and marketed. The very concept is ridiculous, you might say... unless you happened to see advertisements like this one for RCA's Radiotron vacuum tubes from the 1930s. In it, none other than Bing Crosby was joined by a trendily dressed woman who was rejoicing in her decision to buy a new radio that contained those newfangled "Micro-Sensitive" receiver tubes. Now, raise your hand if you would like to see an advertisement with Scarlett Johansson and/or Ashton Kutcher on top of a cell tower.
