Product Selection
L-Band Phase Shifters
The CHP3010-QFG and CHP3010a98F provide 6-bit control across 1.2–1.4 GHz. The QFG version uses a QFN package, while the CHP3010a98F is supplied as a bare Die.
The CHP6013-SRF covers the same L-band frequency range in a ceramic SMD package for designs requiring a hermetic-style packaged solution.
S- and C-Band Phase Shifters
The CHP4012-QEG and CHP4012a98F cover 2.7–3.5 GHz for S-band radar and beamforming systems.
For 5–6 GHz applications, the CHP4014-98F and CHP4014-QEG provide 6-bit phase control with Die and QFN package choices.
X-Band Phase Shifters
The CHP3015-99F offers wide 8.5–11.5 GHz coverage, while the packaged CHP3015-QDG covers 8.5–10.5 GHz.
The CHP4010-99F is designed for 7–9 GHz applications and provides the highest specified input P-1dB in this selection at 26 dBm.
Broadband Phase Shifter
The CHP4511-99F covers 6–18 GHz, making it suitable for broadband microwave systems requiring one phase-control device across multiple frequency bands.
Typical Applications
Phased-array radar systems
Beamforming and antenna steering
Transmit/receive modules
Electronic warfare equipment
Satellite communication terminals
RF and microwave test systems
