Surface Mount Monolithic Ampliefi r ERA-9SM+ 50 DC to 8 GHz The Big Deal Low Gain Micro-X, 0.085 diameter Good Gain flatness, 0.9 dB Broadband matched Suitable for low phase noise applications Product Overview ERA-9SM+ (RoHS compliant) is wideband current driven amplifier fabricated using HBT technology. In addition, the ERA-9SM+, has good input and output return loss over a broad frequency range without the need for external matching components. It has repeatable performance from lot to lot and is enclosed in a 0.085 diameter micro-x package for very good thermal performance. Key Features Feature Advantages Broadband, DC* to 8 GHz A single amplifier covering DC* to 8 band. (* Low frequency cut off determined by Reduced component inventory external coupling capacitors) Ideal for wideband applications such as instrumentation and military Low gain: Ideal for increasing the gain of amplifier chain by low value. 8.6 dB typ. at 0.1 GHz and Typically small gain change may need two components an amplifier and an attenuator. 6.9 dB at 8 GHz Use of ERA-9SM+ reduces component count. Good Gain Flatness: 0.9 dB No need for gain flatness compensation over 8 GHz band to realize published gain flatness. Wideband matched Input return loss: 18-25 dB typ. No external matching required to realize published return loss. Output return loss: 12-37 dB typ. Low additive phase noise, typically Ideal for low phase noise synthesizer applications -173 dBc/Hz 10 KHz offset Notes A.

It has repeatable performance from lot to lot. It is enclosed in a 0.085 diameter micro-x package. simplified schematic and pin description RF-OUT and DC-IN RF-OUT and DC-IN RF IN 3 4 GND GND 2 1 GROUND RF IN Function Pin Number Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen RF IN 1 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 RF-OUT and DC-IN 3 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 GND 2,4 Design to reduce ground path inductance for best performance. Notes A.
