The device is designed to meet all IS-98 sensitivity, intermodulation and single-tone requirements. The operating voltage is 2.7V and is compatible with 1.8V logic for control lines. The RF2489 integrates the dual-band LNA/downconverters with 30dB of gain control and TX LO buffers. Additionally, a divide-by-2 prescaler to allow the use of a single-band VCO is integrated. The design is flexible, in that the bias currents may be set using off-chip current reference resistors for both the LNA and mixer blocks. The device is packaged in a 5mmx5mm leadless plastic package.

C1 should be chosen as high as possible (not greater than 22pF), while maintaining an RP of L1 that allows for the desired ROUT. L2 and C2 serve dual purposes. L2 serves as an output bias choke, and C2 serves as a series DC block. In addition, L2 and C2 may be chosen to form an impedance matching network if the input impedance of the IF filter is not equal to ROUT. Otherwise, L2 is chosen to be large, and C2 is chosen to be large if a DC path to ground is present in the IF filter, or omitted if the filter is DC blocked. NO T L1, C1, and R form a current combiner which performs a differential to single-ended conversion at the IF frequency and sets the output impedance. In most cases, the resonance frequency is independent of R and can be set according to the following equation: Where CEQ is the equivalent stray capacitance and capacitance looking into pins 1 and 2. An average value to use for CEQ is 2.5pF to 3pF. R can then be used to set the output impedance according to the following equation: R= (4 1 -1 R RP OUT )-1 Rev A21 DS070308 7628 Thorndike Road, Greensboro, NC 27409-9421 * For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com. 4 1 13 of 30 RF2489 Evaluation Board Schematic IF@184MHz VCC C26 33 nF C27 33 nF C28 33 nF C29 33 nF 32 R3 DNI C2 7 pF R2 0 C3 6.8 pF VCC 50 strip R6 DNI C6 7 pF L4 270 nH R5 0 L3 120 nH R4 10 k L2 120 nH R1 10 k C4 6.8 pF 1 31 30 29 28 R10 20 k R9 5.1 k L10 10 nH 27 26 25 50 strip C25 33 nF C24 DNI C23 33 nF 6 3 5 J11 MIX L IN BAND SEL OUT IP SET L11 47 nH F2 4 1 GND GND GND GND 2 IF SEL VCC 50 strip L1 270 nH C1 6.8 pF VCC C22 DNI C21 1.8 pF IN J1 FM IF OUT SI GN S 24 23 22 L16 1.5 nH 21 C17 33 nF R12 0 20 19 L12 7.5 nH C18 1 pF 18 L7 7.5 nH 17 16 C14 33 nF C13 33 nF L6 1 nH C15 DNI L15 15 nH C16 33 nF R11 0 14 15 2489310 Rev. 1 5 50 strip J10 LNA L OUT 2 3 L9 47 nH C20 33 nF 50 strip 50 strip J9 LNA L IN J2 CDMA IF OUT 4 /2 C19 33 nF C5 6.8 pF C30 33 nF 5 J8 LNA H IN 6 /2 SELECT J3 LO IN 50 strip R8 68 7 DE VCC C31 0.5 pF J4 HB LO OUT J5 LB LO OUT 8 9 C7 33 nF 10 50 strip W L13 2 nH L14 2 nH 11 12 13 50 strip 50 strip J7 LNA H OUT VCC ENABLE NE C8 33 nF LNA GAIN C9 33 nF L5 47 nH C10 33 nF C11 33 nF C12 DNI F1 GND GND GND GND OUT IN 2 4 1 MIX GAIN TX BUFF ENABLE FO R P2 1 2 3 4 C32 1 F + P3 1 2 3 CON3 VCC GND GND P1-1 P1-2 P1-3 P1-4 1 2 3 4 CON4 /2 SELECT IF SEL IP SET BAND SEL P2-1 ENABLE P3-1 P2-2 P2-3 P2-4 TX BUFF ENABLE MIX GAIN 50 strip J6 MIX H IN LNA GAIN CON4 NO T 14 of 30 7628 Thorndike Road, Greensboro, NC 27409-9421 * For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com. 6 3 P1 Rev A21 DS070308 RF2489 Evaluation Board Schematic JCDMA/GPS IF@110MHz VCC C26 33 nF C27 33 nF C28 33 nF C29 33 nF 32 R3 DNI C2 9 pF R2 0 C3 15 pF VCC 50 strip R6 DNI C6 9 pF L4 220 nH R5 0 L3 220 nH R4 10 k L2 220 nH R1 10 k C4 15 pF 1 31 30 29 R10 22 k R9 5.1 k 50 strip C25 33 nF C24 DNI C23 33 nF 6 3 5 J11 MIX L IN BAND SEL OUT IP SET L11 47 nH F2 4 1 GND GND GND GND 2 IF SEL VCC 50 strip L1 220 nH C1 15 pF VCC SI GN S L10 11 nH C22 DNI 27 26 25 24 23 L16 1.5 nH 22 21 C17 3 pF 20 L12 5.1 nH L7 10 nH 18 L6 3.9 nH 17 C15 DNI C16 33 nF 19 14 15 16 C14 33 nF C13 33 nF 2489310 Rev. 3 JCDMA/GPS 5 IN J1 FM IF OUT 50 strip C21 1.8 pF 28 J10 LNA L OUT 2 L9 47 nH C20 33 nF 50 strip J9 LNA L IN 3 C19 33 nF J2 CDMA IF OUT 4 /2 5 /2 SELECT J3 LO IN C30 33 nF 50 strip 6 7 50 strip R8 68 L13 2 nH L14 6.2 nH DE C5 15 pF 50 strip J8 LNA H IN VCC 50 strip J7 LNA H OUT J4 HB LO OUT J5 LB LO OUT W 9 10 11 8 50 strip 12 13 VCC NE C7 33 nF C8 33 nF LNA GAIN ENABLE C9 33 nF L5 47 nH C10 33 nF C11 33 nF C12 DNI F1 GND GND GND GND OUT IN 2 4 1 MIX GAIN P1-1 P1-2 P1-3 P1-4 1 2 3 4 CON4 /2 SELECT IF SEL IP SET BAND SEL P2-1 P2-2 P2-3 P2-4 1 2 3 4 ENABLE P3-1 1 2 3 CON3 VCC GND GND J6 MIX H IN 50 strip TX BUFF ENABLE MIX GAIN C32 + 1 F LNA GAIN NO T CON4 Rev A21 DS070308 7628 Thorndike Road, Greensboro, NC 27409-9421 * For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com. 6 3 P1 FO R P2 TX BUFF ENABLE P3 15 of 30 RF2489 Evaluation Board Layout Board Size 3.100" x 2.958" Board Thickness 0.064", Board Material FR-4, Multi-Layer NO T 16 of 30 FO R 7628 Thorndike Road, Greensboro, NC 27409-9421 * For sales or technical support, contact RFMD at (+1) 336-678-5570 or sales-support@rfmd.com.

Rev A21 DS070308 RF2489 PCB Design Requirements PCB Surface Finish The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is 3inch to 8inch gold over 180inch nickel. PCB Land Pattern Recommendation PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and tested for optimized assembly at RFMD; however, it may require some modifications to address company specific assembly processes. The PCB land pattern has been developed to accommodate lead and package tolerances. A = 0.64 x 0.28 (mm) Typ. B = 0.28 x 0.64 (mm) Typ. C = 3.50 (mm) Sq. 3.50 Typ. 0.50 Typ.

The solder mask footprint will match what is shown for the PCB metal land pattern with a 3mil expansion to accommodate solder mask registration clearance around all pads. The centergrounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask clearance can be provided in the master data or requested from the PCB fabrication supplier. A = 0.74 x 0.38 (mm) Typ. B = 0.38 x 0.74 (mm) Typ.
