2.3-2.9 GHz 2W 5V Linear Driver Amplifier

Pin Description

 

Pin

Symbol

Description

1

Iref 1

Reference current into internal active bias current mirror. Current into Iref sets device

quiescent current. Also, can be used as on/off control. (for amp 1)

2

Vbias1

Voltage supply for active bias for amp 1. Connect to same supply voltage as Vcc1.

4, 5

RFin

RF Input

3, 6, 7, 8, 9, 10,

14, 18, 20

GND/NC

No internal connection. This pin can be grounded or N/C on PCB. Land pads should be

provided for PCB mounting integrity.

11, 12, 13

RFout

RF Output

15

Vcc2

Supply Voltage for Amp2

16

Iref 2

Reference current into internal active bias current mirror. Current into Iref sets device

quiescent current. Also, can be used as on/off control. (for amp 2)

17

Vbias2

Voltage supply for active bias for amp 2. Connect to same supply voltage as Vcc2.

19

Vcc1

Supply Voltage for Amp1

Backside Paddle

GND

RF/DC ground. Ensure good solder attach for best thermal and electrical performance.

Applications Information

PC Board Layout

PCB Material: 0.0147” Rogers Ultralam 2000, single layer,

1 oz Cu,

spacing = .050”.

The silkscreen markers ‘A’, ‘B’, ‘C’, etc. and ‘1’, ‘2’, ‘3’,

etc. are used as place markers for critical tuning

components

The pad pattern shown has been developed and tested for

optimized assembly at TriQuint Semiconductor. The PCB

land pattern has been developed to accommodate lead and

package tolerances. Since surface mount processes vary

from company to company, careful process development is

recommended.
