CMD284P4  
DC-22 GHz Distributed Amplifier  
®
Product Overview  
The CMD284P4 is a wideband GaAs MMIC distributed  
amplifier housed in a leadless 4x4 mm plastic surface  
mount package. The amplifier operates from DC to 22 GHz  
and delivers 17 dB of gain with a corresponding output 1  
dB compression point of +19 dBm and noise figure of 2.5  
dB at 10 GHz. The CMD284P4 is a 50 ohm matched design  
which eliminates the need for RF port matching.

Recommended PCB Land Pattern  
Qorvo recommends that the user develop the land pattern that will provide the best design for proper solder reflow and  
device attach for their specific application. Please review Qorvo Application Note AN 105 for a recommended land  
pattern approach.  
Recommended Solder Reflow Profile  
Qorvo recommends screen printing with belt furnace reflow to ensure proper solder reflow and device attach. Please  
review Qorvo Application Note AN 102 for a recommended solder reflow profile.

DC-22 GHz Distributed Amplifier  
Applications Information  
Application Circuit  
Note: Drain voltage (Vdd) must be applied through a broadband bias tee or external bias network.  
External DC block is required on RF input.  
Biasing and Operation  
The CMD284P4 is biased with a positive drain supply and positive gate supply. Performance is optimized when the drain  
voltage is set to +8.0 V. The recommended gate voltage is +3.0 V.  
Turn ON procedure:  
1. Apply drain voltage Vdd and set to +8 V  
2. Apply gate voltage Vgg and set to +3 V  
Turn OFF procedure:  
1. Turn off gate voltage Vgg  
2. Turn off drain voltage Vdd  
The preferred biasing procedure has been proven to be robust and should be used whenever possible. However, the  
CMD284P4 does allow for simultaneous biasing (applying Vdd and Vgg at the same time).  
Refer to Application Note 103: Amplifier Biasing Techniques for instructions.
