ELECTRICAL CHARACTERISTICS
FEATURES
DESCRIPTION
NEC's family of high frequency, low cost, surface mount
devices are well suited for portable wireless communications
and cellular radio applications.
The NE685 series of high f
very low voltage/low current, low noise applications. These
products are ideal for applications up to 2.4 GHz where low
cost, high gain, low voltage, and low current are prime con-
cerns.
Notes: 1. Precaution: Devices are ESD sensitive. Use proper handling procedures.
• LOW COST
• SMALL AND ULTRA SMALL SIZE PACKAGES
• LOW VOLTAGE/LOW CURRENT OPERATION
• HIGH GAIN BANDWIDTH PRODUCT: f
• NOISE FIGURES OF 1.5 dB AT 2.0 GHZ
