Qorvo Advances C-Band Radar Front Ends With BAW-Based Frequency Agility And GaN Power
Switchable BAW filtering and high-efficiency GaN PAs give pulsed ESA radars frequency-agile reception and high-power transmission with fewer RF components
Qorvo, a leading global provider of connectivity and power solutions, today announced a C-band radar solution that adds receiver frequency agility and reduces DC power and heat in the transmit chain. Designed for pulsed ESA systems, the solution combines the industry’s first integrated C-band BAW-switched filter bank with high-efficiency 50 Watt and 200 Watt GaN power amplifiers.
C-Band Architecture
At C-band, frequency agility across 5.2 to 5.9 GHz has meant assembling discrete filters, switches and RF routing because an integrated switched filter bank has not been available. At high transmit power, lower PA efficiency increases DC power and heat, and limited gain adds an external high-power driver stage.
The QPB1055 integrates BAW filtering with switching, routing and control, providing contiguous coverage with a combination of high Q, low insertion loss and small size unavailable in a discrete implementation. On transmit, both PAs reduce DC power and heat with high efficiency. The 50 W QPA2311 delivers 55% PAE, and the 200 W QPA0018 eliminates the external high-power driver stage.
“We are investing across the C-band radar front end where frequency agility and transmit efficiency are problems the market has left open,” said Diwakar Vishakhadatta, VP, Defense & Aerospace Products at Qorvo. “For customers, this means less custom receive design and higher transmit power without growing the DC power budget.”
Receiver Frequency Agility and Transmit Efficiency
| Product | Function | Frequency Range | Key Differentiators | System Impact |
| QPB1055 | 7-channel + Bypass Switched Filter Bank | 5.2 to 5.9 GHz | 40 dBc close-in rejection and 480 ns switching across seven channels | Enables receiver agility while replacing discrete filters, switches and routing |
| QPA2311 | 50 Watt GaN Power Amplifier | 5.3 to 5.9 GHz | > 55% PAE across the 5 to 6 GHz band with drop-in compatibility to TGA2307-SM | Reduces DC power and heat without changing the existing PA footprint |
| QPA0018 | 200 Watt GaN Power Amplifier | 5.2 to 5.9 GHz | Two-stage 200 W MMIC with >20dB gain and >50% efficiency across the band | Eliminates the need for an external high-power driver stage and its DC load |
The QPB1055, QPA2311 and QPA0018 join Qorvo’s C-band limiters, LNAs, switches and driver amplifiers. The expanded portfolio gives radar customers receive and transmit building blocks backed by Qorvo’s BAW, GaN and system-level RF expertise.
