Guerrilla RF Offers De-embedded S-Parameters with Noise Data

Guerrilla RF now offers several low noise amplifiers (LNA) with de-embedded s-parameters which include noise parameters. These data sets allow design engineers to accurately simulate the tradeoffs between LNA gain, noise figure (NF) and filter performance associated with various matching networks and matching component types.
 
Below is a growing list of devices for which these data sets are currently available. Links to these new s-par/noise data sets can be accessed via the Guerrilla RF website landing pages for the various devices.
 
Ultra-low noise infrastructure-class amplifiers:
 
GRF2070 / GRF2080
GRF2071 / GRF2081
GRF2072 / GRF2082
GRF2073 / GRF2083
 
Please note that a GRF207X device and its counterpart GRF208X device differ only in the shutdown features of the devices. The core amplifiers are identical. Thus, for instance, the data set for GRF2070 is also applicable to GRF2080.
 
Industry’s highest-gain, lowest-noise figure devices built in our next-generation E/D-mode pHEMT process:
 
GRF2093
GRF2074
 
High-linearity LNAs for second-stage LNA applications:
 
GRF4002
GRF4014
 
Low-current LNAs for GPS/WLAN and other applications:
 
GRF2100
GRF2106
GRF2505
 
What are a couple of examples of how these s-parameters with noise data might be used?

Two pairs of our LNAs stand out as our leading Satellite Digital Audio Radio Service (SDARS) automotive LNA solutions embedded into a dual SAW filter lineup:
   
In conjunction with s-parameters from the chosen filter manufacturer, these new data sets allow for an accurate simulation of the various gain, NF and filter performance tradeoffs associated with the cascaded SDARS LNA design.
 
Next month, we will examine the practical aspects of realizing an application  circuit with the lowest possible NF using ultra-low noise pHEMT devices.

Regardless of your design task, the Guerrilla RF applications engineering team is ready to help. Our goal is to make your product successful.
