The T7024 is a monolithic SiGe transmit/receive front-end IC with power amplifier, low-noise amplifier and T/R switch driver. It is especially designed for operation in TDMA systems like Bluetooth® and WDCT. Due to the ramp-control feature and a very low quiescent current, an external switch transistor for VS is not required.
The Atmel T7024 is a single-chip solution designed for operation in TDMA systems like Bluetooth and WDCT. It integrates a high-power-added efficient power amplifier, a low-noise preamplifier with typically 2.1 dB noise figure, and a T/R switch driver. The device operates on a single 3-V supply voltage and features ramp-controlled output power to simplify external circuit design.
| Supply Voltage | 2.7 V to 4.6 V (PA), 2.7 V to 5.5 V (LNA) |
|---|---|
| Frequency Range | 2.4 GHz to 2.5 GHz |
| Power Gain (Max) | 33 dB |
| Saturated Output Power | Up to 24 dBm |
| Noise Figure (Typical) | 2.1 dB |
| Supply Current (TX, PSSO20) | 190 mA |
The low-noise preamplifier has a typical noise figure of 2.1 dB.
No, due to its ramp-control feature and low quiescent current, an external switch transistor is not required.
The device is available in PSSO20 and QFN20 packages.
