PRODUCT DESCRIPTION
CHP2299 is an InGaP HBT amplifier module
offering high performance for WCDMA wireless
handsets. It consists of a two-stage amplifier, 50 Ω
matching network for both input and output, and a
bias control circuit. It is packaged in a 3 x 3 x 1 mm
package using proprietary Passive-Free Technology
(PFT)TM. The package excellent electrical stability
and low thermal resistance.

Notes:
1. VREF = 0V forces all currents to zero excluding the current of
VMODE pin. To shut down the VMODE current VMODE should be zero as well.
Using the AGC Option
If the analog gain control (AGC) option is needed,
then for a typical operation, Vmode can be defined
as a linear function of output power:
VMODE = 1.5 V + 0.025* POUT(dBm)
The following tables list the electrical performance,
of CHP2299 with AGC option as well as the power
mode truth table.

The device may be operated safely over these conditions; however, parametric performance is guaranteed
only over the conditions defined in the electrical specifications.
Notes:
(1) Gain and idle current for VMODE less than VMODEMin are the same as that of VMODE = VMODEMin. Also the Gain and idle
current for VMODE higher than VMODEMax are the same as that of VMODE = VMODEMax.
