Synthesizer/Modulator from RFMW offers Programmable Bandwidth

Qorvo RFMD2081 IQ Modulator w/Synthesizer/VCO&Baseband Interface, 45MHz - 2700MHzRFMW, Ltd. announces design and sales support for a low power, highly integrated, wideband, IQ modulator with integrated fractional-N synthesizer and voltage controlled oscillator (VCO). Qorvo’s RFMD2081 modulator features an input 3dB bandwidth of 100MHz, and can generate output frequencies of between 45MHz and 2700MHz, making it suitable for a wide range of applications such as satellite communications, QPSK/QAM modulators, wireless broadband, point to point radios and Software Defined Radios (SDR). The RFMD2081’s fractional-N synthesizer offers very low spurious levels with typical step size of 1.5Hz. Typical noise floor is -162dBm/Hz. Programable via serial interface, P1dB is 4dBm and the device runs from a 2.7-3.3V supply consuming 135mA. Qorvo offers this I/Q modulator in a compact 5x5mm QFN package.
