We see from your search that you're looking for information on the term "Mobile handsets",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Speaker driver boosts audio performance from
Wolfson Microelectronics, which we summarised at the time by saying "Small device footprint allows placement close to the speaker housing, enabling simplified PCB layout and maintaining signal integrity".
The day before,
we featured the news release Power amps cut handset transmission drain from
Avago Technologies: "Active bypass mode in power amplifiers provides tremendous benefit to extending handset battery life in today's CDMA and UMTS/GSM networks".
In February 2008, we covered the news from RF Micro Devices
concerning its Polaris 3 Silver
- take a look at RF shielding protects mobile handsets
which says: "The Polaris 3 RF solution integrates all the functions of the RF section of quad-band EDGE mobile handsets, including the power amplifier, SAW filters, crystal oscillator, switch and transceiver".
Take a look also at the news release from NXP Semiconductors, Assisted-GPS device is first fruit of acquisition,
as well as Flash/RAM combinations provide speed boost from Silicon Storage Technology,
and Location IC makes new use of GPS data from Air Semiconductor.
