ERA-3SM+
CASE STYLE: WW107
PRICE: $1.72 ea. QTY. (30)
+ RoHS compliant in accordance
with EU Directive (2002/95/EC)
The +Suffix has been added in order to identify RoHS
Compliance. See our web site for RoHS Compliance methodologies and qualifications.
ERA-3SM+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable performance from lot to lot. It is enclosed in a Micro-X package. ERA-3SM+ uses Darlington configuration and is fabricated using InGaP HBT technology. Expected MTBF is 9,000 years at 85°C case temperature.

Description
RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation.
RF output and bias pin. DC voltage is present on this pin; therefore a DC blocking capacitor is necessary for proper operation. An RF choke is needed to feed DC bias without loss of RF signal due to the bias connection, as shown in “Recommended
Application Circuit”.
Connections to ground. Use via holes as shown in “Suggested Layout for PCB
Design” to reduce ground path inductance for best performance.
