Cellular transmitter and receiver

20 February 2013 Telecoms, Datacoms, Wireless, IoT

Hittite has released a new receiver (Rx) and transmitter (Tx) radio frequency integrated circuit (RFIC) chipset which is ideal for frequency conversion applications in wireless infrastructure equipment such as base transceiver stations, remote radio units, small cells and repeaters from 700 to 3500 MHz.

The HMC1190LP6GE is a high-linearity, dual-channel down-converter with integrated PLL/VCO which is designed specifically for multi-standard receiver applications that require a compact and low-power solution.

The device delivers 8 dB conversion gain, with IP3 and input P1dB performance of +24 dBm and +11 dBm respectively. In support of high-IF receivers and antenna diversity architectures, 2 x 2 spurious products are typically below -70 dBc.

The chip’s RF and LO inputs are single-ended while an enable/disable pin makes it possible to reduce power consumption dynamically as conditions allow. Balanced high-linearity passive mixer cores combined with high-linearity IF amplifiers deliver excellent LO-to-RF, LO-to-IF and RF-to-IF isolation.

For transmit applications, the HMC1197LP7FE is a low-noise, high-linearity direct quadrature modulator with integrated fractional-N PLL/VCO which is rated for operation from 100 to 4000 MHz. This wideband transmitter solution delivers output IP3 of +30 dBm, with up to +10,5 dBm of output power and a very low noise floor of -160 dBm/Hz.

The single-ended RF output port is matched to 50 Ω with no external components while the auxiliary LO output enables the IC to distribute identical frequency and phase signals to multiple destinations within the transmitter or receiver.

An integrated programmable bandwidth low pass filter (LPF) in the LO path ensures little or no LO contribution to modulator sideband rejection. Sixteen programmable LPF bands enable true wideband operation and allow agile LO frequency filtering for different band plans during and after deployment.

Both the HMC1190LP6GE and HMC1197LP7FE incorporate a feature-rich PLL and wideband VCO. The PLL features a very low figure of merit (FOM) of -230 dBm/Hz in integer mode, while the internal VCO section can generate frequencies from 50 to 4100 MHz.

The integrated phase detector and delta-sigma modulator within the devices are capable of operating at up to 100 MHz, permitting wider loop-bandwidths with excellent spectral performance. The PLL/VCOsection can phase adjust and synchronise multiple Hittite Tx and Rx RFICs, enabling scalable MIMO and beam-forming radio architectures.

Additional PLL/VCO features include a configurable output mute function and an exact frequency mode that enables both products to generate fractional frequencies with 0 Hz frequency error and the ability to synchronously change frequencies without changing the phase of the output signal.
