General Description

ERA-3SM+ (RoHS compliant) is a wideband ampliﬁer offering high dynamic range. It has repeatable per-

formance 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.

Function

Pin Number

Description

RF input pin. This pin requires the use of an external DC blocking capacitor chosen

for the frequency of operation.

RF IN

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

操作。RF扼流圈需要养活DC偏置而不RF信号的损失，由于偏置连接，如图中的“推荐的应用电路”。

Connections to ground. Use via holes as shown in “Suggested Layout for PCB
