CHM1270A98F

CHM1270a98F W-Band Dual Channel Transmitter/Receiver GaAs Monolithic Microwave IC Description The CHM1270a98F is a dual channel self-biased transmitter/receiver. One RF port used for reception and one for both emission and reception. This product is designed for optimum IF noise performances. This circuit is well adapted to the sensors system at W-Band, such as automotive long range radar and industrial sensors. This circuit is manufactured with the BES MMIC process: 1 µm very high Ft Schottky diode device, air bridges, via holes through the substrate. It is available in chip form with BCB top layer protection. Main Features ■ Very low 1/f noise ■ High LO/AM noise rejection ■ Low conversion loss ■ IF from DC to 100MHz ■ No DC bias required for mixer ■ On chip temperature sensor embedded ■ ESD strengthened ■ Chip size: 2.95 x 2.00 x 0.10mm IFa_Lc (dB) Vtemp LO RFa / Tx 0° 76. 5GHz 90° RFb Rx BES IFa IFb Transmitter/Receiver block diagram 20 18 16 14 12 10 8 6 4 2 0 74,5 75 75,5 76 76,5 77 77,5 78 78,5 F_lo (GHz) On wafer typical IFa_Lc measurement Main Electrical Characteristics Tamb.= +25°C Symbol Parameter FLO, FRF RF & LO Frequency range FIF IF Frequency range LcIFa LcIFb IFa conversion loss IFb conversion loss NIF IF port noise power @ IF=100kHz Min Typ Max Unit 76 77 GHz DC 100 MHz 11.0 dB 7.5 dBm -162 dBm/Hz Ref. : DSCHM1270a2352 - 17 Dec 12 1/8 Specifications subject to change without notice United Monolithic Semiconductors S.A.S.
