AG101
Product Description
The AG101 is a general purpose gain block that
offers good dynamic range in a low cost surface
mount package. The combination of flat OIP3
and noise figure performance over frequency
makes it attractive for for both narrow band
and broadband applications. Superior thermal
design allows the product to achieve +32 dBm
OIP3 performance at a mounting temperature
of +85°C with an associated MTBF of >1000
years
3
. All devices are 100% RF and DC tested.
