Modem (modulator-demodulator)
Hittite Microwave
The HMC495LP3(E) is a low noise Wideband Direct Quadrature Modulator RFIC which is ideal for digital modulation applications from 250 - 3800 MHz including; Cellular/3G, Broadband Wireless Access & ISM circuits. Housed in a compact 3x3 mm (LP3) SMT QFN package, the RFIC requires minimal external components & provides a low cost alternative to more complicated double upconversion architectures.
