GVA-91+

Overview

The GVA-91+ is a monolithic RF amplifier from Mini-Circuits, fabricated using GaAs HBT technology. It operates within the frequency range of 869 MHz to 2.17 GHz and is housed in an SOT-89 surface-mount package. The device provides a typical gain of 15.4 dB with a noise figure of 4.5 dB at a test frequency of 869 MHz. It requires a supply voltage between 4.8 V and 5.2 V and draws a supply current of 147 mA. Key performance metrics include a P1dB compression point of 29.5 dBm and an OIP3 of 43.4 dBm. The amplifier supports power dissipation up to 1.7 W and functions reliably across a temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix (e.g., TR, CT, DKR) required for your manufacturing process, as these denote different packaging formats such as tape-and-reel or cut tape. Confirm RoHS compliance status and ensure the selected variant matches the intended volume requirements. Cross-reference the manufacturer part number with distributor catalogs to validate current availability and lead times before finalizing procurement plans.

Selection Notes

Select the GVA-91+ when designing circuits requiring moderate gain and low noise in the sub-2.2 GHz band. Ensure the power supply can deliver 147 mA continuously and that thermal management accommodates the specified power dissipation. This component is suitable for space-constrained designs due to its small footprint, provided the operating temperature remains within the industrial range limits defined by the manufacturer.

Part Context

This component belongs to the GVA series of general-purpose monolithic amplifiers produced by Mini-Circuits. The series is characterized by robust GaAs construction and consistent performance across various RF frequencies. The GVA-91+ specifically targets cellular infrastructure bands, offering a balance of gain, linearity, and noise performance suitable for modern wireless standards.

Replacement Considerations

Consult official Mini-Circuits documentation for direct cross-references. Verify pinout compatibility and electrical parameter overlaps if substituting with other GVA series variants or competing manufacturers' parts to ensure circuit stability.
