(LFCSP). THERMAL CONSIDERATIONS The ADL5605 is packaged in a thermally efficient 4 mm × 4 mm, 16-lead LFCSP. The thermal resistance from junction to air (θ ) is 52.1°C/W. The thermal resistance for the product JA was extracted assuming a standard 4-layer JEDEC board with 25 copper plated thermal vias. The thermal vias are filled with 16 13 conductive copper paste (AE3030 with thermal conductivity of 7.8 W/mK and thermal expansion α1 of 4 × 10−5/°C and α2 of RFIN 8.6 × 10−5/°C). The thermal resistance from junction to case (θ ) JC RFOUT is 12.1°C/W, where the case is the exposed pad of the lead frame 16 MIL VIA PAD WITH 8 MIL VIA package. For the best thermal performance, it is recommended that as 5 8 many thermal vias as possible be added under the exposed pad of the LFCSP. The thermal resistance values assume a minimum of 25 thermal vias arranged in a 5 × 5 array with a via diameter of 8 mils, via pad of 16 mils, and a pitch of 20 mils. The vias are plated with copper, and the drill hole is filled with a conductive c opper paste. 09353-035 Figure 36. Recommended Land Pattern Rev. B | Page 15 of 18

Power supply decoupling capacitors are required to C3 = 10 pF C8, C9, C10, C11, filter out the high frequency noise on the power supply. The smallest capacitor should be the C5, C7, C12 = 100 pF C12, C13, C14 closest to the ADL5605.

The output match is set for 943 MHz and is easily changed for C = 8.0 pF HQ OUT OUT other frequency tuning bands. The tolerance of this capacitor should be tight. C is set at OUT a specific distance from the device so that the microstrip line can act as inductance for the matching network (see Table 7). If space is at a premium, an inductor can take the place of the microstrip line. A short length of low impedance line on the output is embedded in the match. L2 Output matching inductor. The output match is set for 943 MHz and is easily changed for other L2 = 1.6 nH HQ frequency tuning bands. A high Q Coilcraft inductor with tight tolerance is recommended. L1 The main bias for the ADL5605 comes through L1 to the output stage. L1 should be high L1 = 18 nH impedance for the frequency of operation while providing low resistance for the dc current. The evaluation board uses a Coilcraft 0603HP-18NX_LU inductor; this 18 nH inductor provides some of the match at 943 MHz.
