Sirenza Microdevices (NASDAQ: SMDI) is the top speculative play for 2007 from quantitative analyst Vahan Janjigian. The editor of The Forbes Growth Investor says, "Sirenza designs and supplies radio frequency (RF) components for equipment used in the defense, aerospace, and homeland security markets. It also does business in the commercial communications and consumer markets.

"Broomfield, Colorado-based Sirenza was off to the races in 2006, gaining 193% from the first of the year until July 3. The drop that was to come, however, was swift and ugly, finally culminating four months later after the stock lost more than 48% of its value.

"The shares began to rally after the October 31 acquisition of Micro Linear Corp., a semiconductor company specializing in wireless integrated circuit (IC) solutions used in a variety of wireless applications. Five weeks after its November 2 bottom, the stock had rallied 30%, and I believe there's more to come on the upside.

"SMDI sports a lean PEG ratio of 0.75 and 14.8 times expected 2006 full year earnings of $0.61 per share. For the September quarter, revenue was up 130% over the same quarter in 2005, while earnings per share shot up 189%."
