Integration Drives Base Station Design Evolution

TriQuint Products:
  • Reduce the size of RF PCB areas
  • Reduce complexity
  • Reduce overall cost

System efficiency plays a critical role whether a network operator is expanding coverage areas or initiating new service. Traditional gantry or monopole base stations continue to be replaced by smaller, high-efficiency plants that use remote radio head (RRH) technology. Remote radio heads can reduce real estate expenses, are more efficient, can be deployed more easily and offer inherent maintenance advantages. RRH components need to meet increasingly stringent size and efficiency goals in addition to established standards for reliable, virtually continuous operation unique to the base station environment.

TriQuint solutions enable customers to spend less time and design energy on individual component issues, which frees them to focus on system performance.

Contact TriQuint product marketing to discover more about the ways that TriQuint uses integration to simplify RF connectivity.

Level One

Devices that offer high gain and integrated matching. These products enable designers to eliminate one or more levels of gain in their lineups without external matching circuitry, benefitting size and cost considerations.

Examples: TQP3M9008 & TQP3M9009

 

 
Level Two

Devices that integrate multiple functions in one package for overall size reduction, such as placing a multistage amplifier or mixer with a local oscillator (LO) buffer amplifier. These products enable system size reduction.

Examples: TQP8M9013, ML483-G & ML485-G

 

Level Three

Devices that combine two amplifier stages with interstage matching. They eliminate the need for external matching circuitry between amplifiers while reducing system cost and size.

Examples: AH212 & AH323-G

 
Level Four

These products offer full in-package integration. By combining two amplifiers, a digital step attenuator, all matching components, bias chokes, plus bypass and blocking capacitors, these modules deliver a 50 ohm solution that lowers cost and is more compact.

Examples: TQM879006A

TriQuint and Scintera Offer Linearized PA Solution for 3G / 4G Small Cells

TriQuint and Scintera have developed a design-ready solution to power small cell 3G / 4G / LTE base stations. This solution combines off-the-shelf RF broadband amplifier ICs from TriQuint and advanced linearization techniques from Scintera to offer base station OEMs a means to address the data requirements of capacity-stressed WCDMA networks, as well as satisfy 4G / LTE data rate needs. The solution is designed to support all major global cellular bands including 700, 900, 2100 and 2600 MHz. Unlike traditional base stations that typically employ a 28 volt technology, the TriQuint / Scintera solution is the first to use a 12 volt power amplifier.

This factor can reduce power consumption as well as save space within the housing by eliminating higher voltage converters.

This small cell solution combines Scintera's SC1869 RF power amplifier linearizer with TriQuint's broadband TQP7M9103 and AP561-F. Delivering 2 watts (33 dBm) of linear output power, the solution can support single or multiple carriers up to 20 MHz (total signal bandwidth) for all major cellular bands. Network operators see small cell base stations as a cost-effective way to support 3G / 4G / LTE data rates. "This innovation simplifies RF connectivity by leveraging market-tested solutions and reducing power consumption while also using the same broadband RFICs across multiple bands," said TriQuint Vice President, Brian P. Balut.

TriQuint's portion of the linearized transmitter system consists of the TQP7M9103 driver stage followed by the AP561-F power amplifier. TriQuint's TQP7M9103 and AP561-F provide a design-ready amplification solution with broadband coverage across all 3G / 4G frequency bands. Key specifications of the two devices are noted below.

    • 14.8 dB gain
  • Easy to linearize with SC1869
    • <-50 dBc ACLR (4c WCDMA 7.8 dB PAR)
  • Internal bias and temperature compensation
  • 5x6 mm DFN surface-mount package

Scintera's SC1869

  • Up to 20 MHz instantaneous signal bandwidth
  • PA average output: 500 mW = PAout = 10 W
  • PA architectures: Class A / AB

Figure 2: Scintera’s evaluation board shows the SC1869: 2.5x 2.5cm; no delay. Its SC1889: 2.5x3.6cm, provides printed delay. Both devices provide 4-layer design.

The combination of TriQuint's market-tested driver and power amplifier with Scintera's linearization techniques offer RF designers a straightforward, rapid development solution for satisfying the increasing capacity requirements of WCDMA and LTE networks.

Scintera's analog signal processing architecture effectively combines digital programmability with the simplicity, small size and low power consumption of analog circuit design. By repartitioning portions of the classic predistortion algorithm from the digital domain to the analog / RF domain, Scintera has delivered a predistortion linearization solution with very low power consumption, wide bandwidth performance and a compact system footprint.

Figure 3: TriQuint’s TQM7M9103 and AP561-F are suitable for linearized systems and wide signal bandwidth. Scintera’s SC1869 solution provides greater than 17 dB of correction in the adjacent channel with 1111 4-carrier WCDMA 7.8 dB PAR signal at a center frequency of 2.14 GHz. The solution is designed for 2 W Pavg and supports all global cellular frequencies with up to 20 MHz of instantaneous signal bandwidth.
