The HMC994APM 5E is a GaAs pHEMT MMIC Distributed Wideband Power Amplifier which operates between DC and 28 GHz. The amplifier provides 15 dB of gain, +29 dBm of saturated output power, and 25% PAE from a +10V supply. With up to +38 dBm Output IP 3 the HMC994APM 5E is ideal for high linearity applications in military and space as well as test equipment where high order modulations are used. The HMC994APM 5E exhibits a positive gain slope from 2 to 20 GHz making it ideal for EW , ECM, and test equipment applications. The HMC994APM5E amplifier I/Os are internally matched to 50 Ohms and is packaged in a leadless QFN 5x5 mm surface mount package.

The EV1HMC994APM5 consists of a 2-layer printed circuit board (PCB) fabricated from 10 mil thick, Rogers 4350B, copper clad, mounted to an aluminum heat spreader. The heat spreader assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat spreader allow it to be attached to a heat sink for improved thermal management. The RFIN and RFOUT ports are populated with 2.9 mm, female coaxial connectors, and their respective RF traces have a 50 Ω characteristic impedance. The EV1HMC994APM5 requires an external connectorized bias tee on its RFOUT port to operate.
The EV1HMC994APM5 is populated with components suitable for use over the entire operating temperature range of the HMC994APM5E. To calibrate out board trace losses, a through calibration path, THRU-CAL, is provided between the J5 and J6 connectors. J5 and J6 must be populated with 2.92 mm RF connectors to use the through calibration path. Refer to Figure 3 and Table 2 in the user guide for the through calibration path performance. The power voltages, ground voltages, gate control voltages, and detector output voltages are accessed through two 4-pin headers, J3 and J4 (see Table 1 in the user guide).
The RF traces are 50 Ω, grounded, coplanar waveguide. The package ground leads and the exposed paddle connect directly to the ground plane. Multiple vias are used to connect the top and bottom ground planes with particular focus on the area directly beneath the ground paddle to provide adequate electrical conduction and thermal conduction to the heat spreader.
The decoupling capacitors on the EV1HMC994APM5 represent the configuration used to measure the performance of the circuit, which is detailed in AN-2061. It is possible to reduce the number of capacitors connected to the ACG2, ACG3/ACG4, VGG1, and VGG2 pins, but this reduction varies from system to system. It is recommended to first remove the largest capacitors that are farthest from the HMC994APM5E when reducing the number of capacitors.
For full details on the HMC994APM5E, see the HMC994APM5E data sheet.
Tools & Simulations
Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
