The gain that a modest voltage source in series with the input terminals of an op amp observes is known as the noise gain. The gain from “A” to the output (the non-inverting signal gain) is also the same.
Radio communication systems, medical devices, and electronic test equipment all use LNAs. While reducing the signal-to-noise ratio by less than a factor of two (a 3 dB noise figure (NF)), a conventional LNA may provide a power gain of 100 (20 dB).
The Global Automotive Low-noise gain block market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Guerrilla RF Releases Low Noise Gain Blocks for Automotive SiriusXM Satellite Radio Applications.The GRF4012 and GRF4012W, two broadband gain blocks featuring a distinctive blend of noise and linearity performance over extraordinarily wide bandwidths, have been officially released by Guerrilla RF.
Guerrilla RF created a core designed for satellite radio applications by emphasising a crucial balance between the devices’ gain, noise figure, linearity, and compression performance. The GRF2073W and the most recent SAW filters from Qualcomm Technologies work together to offer a powerful, affordable solution for quickly fulfilling Sirius XM’s blocking requirements.
The GRF4012 and GRF4012W can be configured to operate in a range of frequencies ranging from 0.4 to 4.2 GHz. Each device achieves 17.8 dB of gain, 33 dBm of OIP3 linearity, 22.5 dB of compression, and a noise figure of 0.9 dB while drawing just 50 mA of current at 233.25 MHz (the centre of the SDARS band).
The GRF4012W version, like other devices in Guerrilla RF’s automotive line, has undergone additional qualifying stages to ensure compliance with the demanding AEC-Q100 standard.Each variation comes in a 6-pin, 1.5 mm x 1.5 mm packaging that is pin compliant.
The same packaging and pinout are currently used by over 25 low-noise amplifiers, gain blocks, and driver cores from GRF, enabling customers to readily adapt and optimise their designs for multiple frequencies as well as variable degrees of gain, noise figure, linearity, compression, and power dissipation.
Due to the great degree of design latitude it offers, this modular approach has proven to be very well-liked among GRF’s clientele, translating into design speed and agility.
