AM1
Product Description
The AM1 is a general purpose gain block that
offers good dynamic range in a low cost surface
mount package. The combination of flat IP3
and noise figure performance over frequency
makes it attractive for both narrow and broad-
band applications. Superior thermal design
allows the product to achieve +37 dBm IP3 per-
formance at a mounting temperature of +85°C
with an associated MTBF of >100 years

. All
devices are 100% RF and DC tested.
