XC2401A8167R-G ETR2701-004b 1.6 GHz Low Noise Amplifier ■GENERAL DESCRIPTION The XC2401A8167R-G is an ultra-low-noise amplifier (LNA) with low operating voltage, low noise figure (NF), low power consumption using CMOS process. The device offers easy output matching to 50Ω for input and output with less external components. An internal self bias function eliminates external bias setting. The device operates at 1.2V. For higher power supplies such as 1.8V and 2.85V, the device can operate with a self bias of one adding resister. . ■APPLICATIONS ●GPS RF module ■FEATURES Noise Figure ：NF=0.69dB(TYP.)

Note 1. In case symptoms of transient voltage drop and rise temporarily, please use this IC within the stated maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Please eliminate static electricity from the operational table, people, and soldering iron. 3. Please use noiseless power supply for stable operation. 4. Please use ±1% Rbias with ±200ppm/℃ temperature stability and 10nF Cbias. 5. Please connect Cbias to VDD pin as close as possible. 6. Please ensure to use an external component which does not depend on bias or temperature too much. 7. We will improve the product quality and improve reliability, however please make sure to design fail safe or pre-aging treatment on the system. 5/16 XC2401A8167R-G ■TEST CIRCUITS ●Circuit ① (DC Characteristics: Power Supply Pin Voltage, Circuit Current, Input Power Supply Voltage) * Fixed Bias: Rbias=0Ω, VIN=VDD ** Pin / Pout is 50Ω ●Circuit ② (Power Gain, Input Return Loss, Output Return Loss, Isolation, Input Power @ 1dB Gain Compression) *1: Refer to the circuit ⑤ for the block detail. ●Circuit ③ (Noise Figure) *1: Refer to the circuit ⑤ for the block detail. 6/16 XC2401A8167R-G ■TEST CIRCUITS (Continued) ●Circuit ④ (Input Power IP3) *1: Refer to the circuit ⑤ for the block detail. ●Circuit ⑤ (XC2401 series, the circuit of the block) 100pF RF_IN RF_OUT Rbias VIN VDD VSS Cbias=10nF VIN(V) Rbias(Ω) 3.00 560 * Fixed Bias: Rbias=0Ω, VIN=VDD 2.85 470 ** Rbias: Should be in ±1% tolerance and ±200ppm/℃ temperature stability. 1.80 160 7/16 XC2401A8167R-G ■EVALUATION BOARD 18mm VDD VSS R1 C2 Pout C1 L2 Pin L1 20mm SYMBOL SPEC C1 100pF C2 10nF L1 9.1nH L2 6.2nH R1 (*1) (Rbias) 8/16 - (*1) COMMENT MURATA (GRM1552C1H) TDK (GLQ1005type) TDK ( GLQ1005type) Less than ±1% tolerance, Less than ±200ppm/℃ temperature stability PCB(FR-4) MICROSTRIPLINE WIDTH = 0.6mm t = 0.018mm PCB size = 20mm×18mm *1: Fixed Bias: Rbias=0Ω * Please use an external component which does not depend on bias or temperature too much.
