RF Design
Crossfield develops RF system and
circuit designs to support augmented implementations
of wireless communications standards and RF sensors.
Using industry standard and custom developed RF EDA
(electronic design automation) tools, Crossfield has
developed low noise amplifiers for satellite
communications, RF sensors for industrial and military
applications, downconverters, IF (intermediate
frequency) signal processing, modulators, and power
amplifiers. Our designs are implemented in integrated
circuit form (RFIC/MMIC) as well as traditional
distributed element designs in microstrip. We have
developed circuits for IEEE 802.15.4, IEEE 802.15.4a,
Bluetooth, and WiFi.
Many of Crossfield’s RF designs are custom implemented to
address unique problems in power consumption, interference
rejection, or operational constraints. Crossfield has
developed proprietary enhancements to wireless
communications standards to meet niche market requirements.
Crossfield has also developed embedded antennas for many
wireless applications as well as using off-the-shelf
antennas when feasible.
