Also being shown at the TriQuint booth was a device dubbed the "Diplexer" module. It combines multiple filter functions inside a 5-x-5-mm module. "This is quick-time custom manufacturing, so the customer calls up the factory, picks the filters they want in the module, and we turn these out as if it was a standard product," explains Andrews. TriQuint also unveiled four packaged gallium-arsenide (GaAs) pHEMT RF power-amplifier (PA) modules and several new base-station products for Long Term Evolution (LTE) and related fourth-generation (4G) cellular communications technologies at the show.
