Receiver, Transmitter ICs Span 0.7 To 4.0 GHz

Dec. 4, 2012
A pair of downconverter and upconverter ICs are suitable for receiver and transmitter applications through 4 GHz.

A radio-frequency-integrated-circuit (RFIC) chipset with receiver and transmitter from Hittite Microwave Corp. is suitable for wireless infrastructure frequency-conversion applications from 700 to 3500 MHz. Ideal for use in base-transceiver stations, remote radio units (RRUs), and repeaters, the model HMC1190LP6GE dual-channel downconverter serves the receiver side. It features an integrated phase lock loop (PLL) and voltage-controlled oscillator (VCO). It features 8-dB conversion gain with output power at 1-dB compression of +11 dBm and input third-order intercept point (IIP3) of +24 dBm. Its 2 x 2 spurious products are controlled to below -70 dBc. For transmitters, the model HMC1197LP7FE is a direct quadrature modulator with integrated fractional-N PLL and VCO. Designed for use from 100 MHz to 4 GHz, it provides as much as +10.5 dBm output power at 1-dB compression with IIP3 of +30 dBm. It has a lownoise floor of -160 dBm/Hz. Its single-ended RF output port is matched to 50 Ω with no need for additional external components.
