The devices are offered in an industry standard 2×2 mm DFN-8 package. The RF performance of the devices in the two families is essentially the same. GRF208X offers a shutdown capability on pin 6 making the devices optimal for TDD applications, while GRF207X allows the user to set Iddq independently from Vdd via the enable input to pin1 – thus enabling optimal power consumption for a particular application.

“With their industry leading low NF and high gain, these devices enable the low cascaded receiver noise figures that cellular infrastructure applications require,” said Alan Ake, vice president of applications and technical marketing at Guerrilla RF. “The internal architecture of these devices results in simple external matching which yields excellent fractional bandwidths exceeding 40 percent with a single set of matching component values. These devices deliver incredibly low NF levels. As an example, GRF2071/GRF2081 evaluation board NF at 1.9 GHz is typically 0.35 dB.”

According to Research and Markets, the overall wireless network infrastructure market will witness tremendous growth over the coming years. At a compound annual growth rate of over 5 percent, the market will account for over $104 billion in annual spending by the end of 2020.

The GRF207X and GRF208X LNA families each contain four devices internally optimized to cover the following bands:

  • GRF2070/2080: 0.4 to 1.5 GHz;
  • GRF2071/2081: 1.4 to 2.7 GHz;
  • GRF2072/2082: 2.3 to 3.8 GHz;
  • GRF2073/2083: 3.0 to 6.0 GHz.
