17-25 GHz Low Noise Amplifier
Product Overview
The CMD298C4 is a highly efficient GaAs MMIC low noise
amplifier housed in a leadless 4x4 mm surface mount
package. The CMD298C4 is ideally suited for EW and
communications systems where small size and low power
consumption are needed. The device is optimized for 21
GHz and delivers greater than 27 dB of gain with a
corresponding noise figure of 1.4 dB and output 1 dB
compression point of +8 dBm. The CMD298C4 is a 50 ohm
matched design which eliminates the need for external DC
blocks and 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.

Applications Information
Application Circuit
Biasing and Operation
The CMD298C4 is biased with a positive drain supply and positive gate supply. Sequencing of the drain and gate supply
is not required. Performance is optimized when the drain voltage is set to +3.0 V, though it may be set to a minimum of
+1.5 V and a maximum of +3.5 V. The recommended gate voltage is +1.5 V.
Turn ON procedure:
1. Apply drain voltage Vdd and set to +3 V
2. Apply gate voltage Vgg and set to +1.5 V
Turn OFF procedure:
1. Turn off gate voltage Vgg
2. Turn off drain voltage Vdd
Refer to Application Note 103: Amplifier Biasing Techniques for instructions on how to implement a single supply biasing
scheme.
RF power can be applied at any time.
