TriQuint (TQNT -10.9%) has almost entirely given back its November-January gains after providing weak Q1 guidance to go with a Q4 beat. Management noted on the earnings call chip sales for 3G/4G phones, mobile base stations, and radar equipment are growing quickly, but added declining 2G sales are a headwind, and that low factory utilization is hurting profitability. Sales to mobile OEMs are expected to see "strong seasonality" in Q1, but management talked up the 2013 impact of 2012 mobile R&D investments. SWKS -1.9%. AVGO -1.9%. ANAD -3.8%.
